Struct wgpu_hal::gles::Adapter

pub struct Adapter {
    shared: Arc<AdapterShared>,
}

Fields

shared: Arc<AdapterShared>

Implementations

impl Adapter

pub unsafe fn new_external( fun: impl FnMut(&str) -> *const c_void, ) -> Option<ExposedAdapter<Api>>

Creates a new external adapter using the specified loader function.

Safety

• The underlying OpenGL ES context must be current.
• The underlying OpenGL ES context must be current when interfacing with any objects returned by wgpu-hal from this adapter.
• The underlying OpenGL ES context must be current when dropping this adapter and when dropping any objects returned from this adapter.

pub fn adapter_context(&self) -> &AdapterContext

impl Adapter

fn parse_version(src: &str) -> Result<(u8, u8), InstanceError>

Note that this function is intentionally lenient in regards to parsing, and will try to recover at least the first two version numbers without resulting in an Err.

Notes

WebGL 2 version returned as OpenGL ES 3.0

pub(super) fn parse_full_version(src: &str) -> Result<(u8, u8), InstanceError>

According to the OpenGL specification, the version information is expected to follow the following syntax:

<major>       ::= <number>
<minor>       ::= <number>
<revision>    ::= <number>
<vendor-info> ::= <string>
<release>     ::= <major> "." <minor> ["." <release>]
<version>     ::= <release> [" " <vendor-info>]

Note that this function is intentionally lenient in regards to parsing, and will try to recover at least the first two version numbers without resulting in an Err.

fn make_info( vendor_orig: String, renderer_orig: String, version: String, ) -> AdapterInfo

pub(super) unsafe fn expose( context: AdapterContext, ) -> Option<ExposedAdapter<Api>>

unsafe fn compile_shader( source: &str, gl: &Context, shader_type: u32, es: bool, ) -> Option<Shader>

unsafe fn create_shader_clear_program( gl: &Context, es: bool, ) -> Option<ShaderClearProgram>
