Struct webrender::device::gl::TextureUploader

pub struct TextureUploader<'a> {
    buffers: Vec<PixelBuffer<'a>>,
    pub pbo_pool: &'a mut UploadPBOPool,
}

Used to perform a series of texture uploads. Create using Device::upload_texture(). Perform a series of uploads using either upload(), or stage() and upload_staged(), then call flush().

Fields

buffers: Vec<PixelBuffer<'a>>

A list of buffers containing uploads that need to be flushed.

pbo_pool: &'a mut UploadPBOPool

Pool used to obtain PBOs to fill with texture data.

Implementations

impl<'a> TextureUploader<'a>

pub fn stage( &mut self, device: &mut Device, format: ImageFormat, size: DeviceIntSize ) -> Result<UploadStagingBuffer<'a>, String>

Returns an UploadStagingBuffer which can be used to manually stage data to be uploaded. Once the data has been staged, it can be uploaded with upload_staged().

pub fn upload_staged( &mut self, device: &mut Device, texture: &'a Texture, rect: DeviceIntRect, format_override: Option<ImageFormat>, staging_buffer: UploadStagingBuffer<'a> ) -> usize

Uploads manually staged texture data to the specified texture.

pub fn upload<T>( &mut self, device: &mut Device, texture: &'a Texture, rect: DeviceIntRect, stride: Option<i32>, format_override: Option<ImageFormat>, data: *const T, len: usize ) -> usize

Uploads texture data to the specified texture.

fn flush_buffer( device: &mut Device, pbo_pool: &mut UploadPBOPool, buffer: PixelBuffer<'_> )

pub fn flush(self, device: &mut Device)

Flushes all pending texture uploads. Must be called after all required upload() or upload_staged() calls have been made.

fn update_impl(device: &mut Device, chunk: UploadChunk<'_>)

Trait Implementations

impl<'a> Drop for TextureUploader<'a>

fn drop(&mut self)

Executes the destructor for this type.
