Implementations§

source§

impl<T: EGL1_0> Instance<T>

source

pub fn matching_config_count( &self, display: Display, attrib_list: &[Int], ) -> Result<usize, Error>

Return the number of EGL frame buffer configurations that atch specified attributes.

This will call eglChooseConfig without null as configs to get the number of matching configurations.

This will return a BadParameter error if attrib_list is not a valid attributes list (if it does not terminate with NONE).

source

pub fn choose_config( &self, display: Display, attrib_list: &[Int], configs: &mut Vec<Config>, ) -> Result<(), Error>

Return a list of EGL frame buffer configurations that match specified attributes.

This will write as many matching configurations in configs up to its capacity. You can use the function matching_config_count to get the exact number of configurations matching the specified attributes.

§Example
// Get the number of matching configurations.
let count = egl.matching_config_count(display, &attrib_list)?;

// Get the matching configurations.
let mut configs = Vec::with_capacity(count);
egl.choose_config(display, &attrib_list, &mut configs)?;

This will return a BadParameter error if attrib_list is not a valid attributes list (if it does not terminate with NONE).

source

pub fn choose_first_config( &self, display: Display, attrib_list: &[Int], ) -> Result<Option<Config>, Error>

Return the first EGL frame buffer configuration that match specified attributes.

This is an helper function that will call choose_config with a buffer of size 1, which is equivalent to:

let mut configs = Vec::with_capacity(1);
egl.choose_config(display, &attrib_list, &mut configs)?;
configs.first();
source

pub unsafe fn copy_buffers( &self, display: Display, surface: Surface, target: NativePixmapType, ) -> Result<(), Error>

Copy EGL surface color buffer to a native pixmap.

§Safety

target must be a valid pointer to a native pixmap that belongs to the same platform as display and surface.

source

pub fn create_context( &self, display: Display, config: Config, share_context: Option<Context>, attrib_list: &[Int], ) -> Result<Context, Error>

Create a new EGL rendering context.

This will return a BadParameter error if attrib_list is not a valid attributes list (if it does not terminate with NONE).

source

pub fn create_pbuffer_surface( &self, display: Display, config: Config, attrib_list: &[Int], ) -> Result<Surface, Error>

Create a new EGL pixel buffer surface.

This will return a BadParameter error if attrib_list is not a valid attributes list (if it does not terminate with NONE).

source

pub unsafe fn create_pixmap_surface( &self, display: Display, config: Config, pixmap: NativePixmapType, attrib_list: &[Int], ) -> Result<Surface, Error>

Create a new EGL offscreen surface.

This will return a BadParameter error if attrib_list is not a valid attributes list (if it does not terminate with NONE).

§Safety

This function may raise undefined behavior if the display and native pixmap do not belong to the same platform.

source

pub unsafe fn create_window_surface( &self, display: Display, config: Config, window: NativeWindowType, attrib_list: Option<&[Int]>, ) -> Result<Surface, Error>

Create a new EGL window surface.

This will return a BadParameter error if attrib_list is not a valid attributes list (if it does not terminate with NONE).

§Safety

This function may raise undefined behavior if the display and native window do not belong to the same platform.

source

pub fn destroy_context( &self, display: Display, ctx: Context, ) -> Result<(), Error>

Destroy an EGL rendering context.

source

pub fn destroy_surface( &self, display: Display, surface: Surface, ) -> Result<(), Error>

Destroy an EGL surface.

source

pub fn get_config_attrib( &self, display: Display, config: Config, attribute: Int, ) -> Result<Int, Error>

Return information about an EGL frame buffer configuration.

source

pub fn get_config_count(&self, display: Display) -> Result<usize, Error>

Return the number of all frame buffer configurations.

You can use it to setup the correct capacity for the configurations buffer in get_configs.

§Example
let mut configs = Vec::with_capacity(egl.get_config_count(display)?);
egl.get_configs(display, &mut configs);
assert!(configs.len() > 0);
source

pub fn get_configs( &self, display: Display, configs: &mut Vec<Config>, ) -> Result<(), Error>

Get the list of all EGL frame buffer configurations for a display.

The configurations are added to the configs buffer, up to the buffer’s capacity. You can use get_config_count to get the total number of available frame buffer configurations, and setup the buffer’s capacity accordingly.

§Example
let mut configs = Vec::with_capacity(egl.get_config_count(display)?);
egl.get_configs(display, &mut configs);
source

pub fn get_current_display(&self) -> Option<Display>

Return the display for the current EGL rendering context.

source

pub fn get_current_surface(&self, readdraw: Int) -> Option<Surface>

Return the read or draw surface for the current EGL rendering context.

source

pub unsafe fn get_display( &self, display_id: NativeDisplayType, ) -> Option<Display>

Return an EGL display connection.

§Safety

The native_display must be a valid pointer to the native display. Valid values for platform are defined by EGL extensions, as are requirements for native_display. For example, an extension specification that defines support for the X11 platform may require that native_display be a pointer to an X11 Display, and an extension specification that defines support for the Microsoft Windows platform may require that native_display be a pointer to a Windows Device Context.

source

pub fn get_error(&self) -> Option<Error>

Return error information.

Return the error of the last called EGL function in the current thread, or None if the error is set to SUCCESS.

Note that since a call to eglGetError sets the error to SUCCESS, and since this function is automatically called by any wrapper function returning a Result when necessary, this function may only return None from the point of view of a user.

source

pub fn create_image( &self, display: Display, ctx: Context, target: Enum, buffer: ClientBuffer, attrib_list: &[Attrib], ) -> Result<Image, Error>

Create a new Image object.

Note that the constant ATTRIB_NONE which has the type Attrib can be used instead of NONE to terminate the attribute list.

§Safety

The native_display must be a valid pointer to the native display. Valid values for platform are defined by EGL extensions, as are requirements for native_display. For example, an extension specification that defines support for the X11 platform may require that native_display be a pointer to an X11 Display, and an extension specification that defines support for the Microsoft Windows platform may require that native_display be a pointer to a Windows Device Context.

source

pub unsafe fn create_platform_window_surface( &self, display: Display, config: Config, native_window: NativeWindowType, attrib_list: &[Attrib], ) -> Result<Surface, Error>

Create a new EGL on-screen rendering surface.

Note that the constant ATTRIB_NONE which has the type Attrib can be used instead of NONE to terminate the attribute list.

This will return a BadParameter error if attrib_list is not a valid attributes list (if it does not terminate with ATTRIB_NONE).

§Safety

The native_window must be a valid pointer to the native window and must belong to the same platform as display. EGL considers the returned EGLSurface as belonging to that same platform. The EGL extension that defines the platform to which display belongs also defines the requirements for the native_window parameter.

source

pub unsafe fn create_platform_pixmap_surface( &self, display: Display, config: Config, native_pixmap: NativePixmapType, attrib_list: &[Attrib], ) -> Result<Surface, Error>

Create a new EGL offscreen surface.

This will return a BadParameter error if attrib_list is not a valid attributes list (if it does not terminate with ATTRIB_NONE).

§Safety

The native_pixmap must be a valid pointer to a native pixmap. and must belong to the same platform as display. EGL considers the returned EGLSurface as belonging to that same platform. The EGL extension that defines the platform to which display belongs also defines the requirements for the native_pixmap parameter.

source

pub fn wait_sync( &self, display: Display, sync: Sync, flags: Int, ) -> Result<(), Error>
