Struct Adapter 

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

Available on gles only.

Fields

shared: Arc<AdapterShared>

Implementations

impl Adapter

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

Available on neither Windows nor webgl.

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

Available on neither Windows nor webgl.

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, backend_options: GlBackendOptions, ) -> 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>

Trait Implementations

impl Adapter for Adapter

type A = Api

unsafe fn open( &self, features: Features, _limits: &Limits, _memory_hints: &MemoryHints, ) -> Result<OpenDevice<Api>, DeviceError>

unsafe fn texture_format_capabilities( &self, format: TextureFormat, ) -> TextureFormatCapabilities

Return the set of supported capabilities for a texture format.

unsafe fn surface_capabilities( &self, surface: &Surface, ) -> Option<SurfaceCapabilities>

Returns the capabilities of working with a specified surface.

unsafe fn get_presentation_timestamp(&self) -> PresentationTimestamp

Creates a PresentationTimestamp using the adapter’s WSI.

fn get_ordered_buffer_usages(&self) -> BufferUses

The combination of all usages that the are guaranteed to be be ordered by the hardware. If a usage is ordered, then if the buffer state doesn’t change between draw calls, there are no barriers needed for synchronization.

fn get_ordered_texture_usages(&self) -> TextureUses

The combination of all usages that the are guaranteed to be be ordered by the hardware. If a usage is ordered, then if the buffer state doesn’t change between draw calls, there are no barriers needed for synchronization.
