Enum webgl_rs::glenum::ProgramParameter

pub enum ProgramParameter {

}

Constants passed to WebGLRenderingContext.getProgramParameter() TODO decide if im keeping it public or move to shader_program as it is only used internally i think

Variants

DeleteStatus

Passed to getProgramParameter to determine if a shader was deleted via deleteProgram. Returns true if it was, false otherwise.

LinkStatus

Passed to getProgramParameter after calling linkProgram to determine if a program was linked correctly. Returns false if there were errors. Use getProgramInfoLog to find the exact error.

ValidateStatus

Passed to getProgramParameter after calling validateProgram to determine if it is valid. Returns false if errors were found.

AttachedShaders

Passed to getProgramParameter after calling attachShader to determine if the shader was attached correctly. Returns false if errors occurred.

ActiveAttributes

Passed to getProgramParameter to get the number of attributes active in a program.

ActiveUniforms

Passed to getProgramParameter to get the number of uniforms active in a program.

TransformFeedbackBufferMode

Passed to getProgramParameter to get the buffer mode when transform feedback is active.

TransformFeedbackVaryings

Passed to getProgramParameter to get the number of varying variables to capture in transform feedback mode

ActiveUniformBlocks

Passed to getProgramParameter to get the number of uniform blocks containing active uniforms

Trait Implementations

impl Clone for ProgramParameter

fn clone(&self) -> ProgramParameter

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProgramParameter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromWasmAbi for ProgramParameter

type Abi = u32

The wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for ProgramParameter

type Abi = u32

The wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for ProgramParameter

fn is_none(val: &u32) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for ProgramParameter

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl WasmDescribe for ProgramParameter

fn describe()

impl Copy for ProgramParameter
