Struct Uniform 

pub struct Uniform<ProgramId: Id, UniformId: Id> { /* private fields */ }

Contains the build information for a WebGL uniform.

A Uniform can be associated with any number of programs, and can be updated with crate::RendererData::update_uniform or crate::RendererData::update_uniforms.

Implementations

impl<ProgramId: Id, UniformId: Id> Uniform<ProgramId, UniformId>

pub fn program_ids(&self) -> &Vec<ProgramId>

Gets all program ids associated with this uniform

pub fn uniform_id(&self) -> &UniformId

Gets this uniform’s uniform id

pub fn uniform_locations(&self) -> &HashMap<ProgramId, WebGlUniformLocation>

Gets this uniform’s location for all associated program ids

pub fn initialize_callback(&self) -> UniformCreateUpdateCallback

Gets the callback that is used to initialize this uniform

pub fn should_update_callback(&self) -> Option<UniformShouldUpdateCallback>

Gets the callback that is used to determine whether this uniform should update when crate::RendererData::update_uniform or crate::RendererData::update_uniforms is called.

pub fn update_callback(&self) -> Option<UniformCreateUpdateCallback>

Gets the callback that is used to updated this uniform whenever crate::RendererData::update_uniform or crate::RendererData::update_uniforms is called.

pub fn use_init_callback_for_update(&self) -> bool

If set to true, Uniform will use the Uniform::initialize_callback callback to update when crate::RendererData::update_uniform or crate::RendererData::update_uniforms is called rather than the Uniform::update_callback

pub fn update( &self, gl: &WebGl2RenderingContext, now: f64, programs: &HashMap<ProgramId, WebGlProgram>, )

Updates the value of this uniform in WebGl for every Program where this uniform is used, using the update callback that was passed in at creation time.

@todo: calling this function for anything more than the current program is useless without a UBO

Trait Implementations

impl<ProgramId: Clone + Id, UniformId: Clone + Id> Clone for Uniform<ProgramId, UniformId>

fn clone(&self) -> Uniform<ProgramId, UniformId>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<ProgramId: Id, UniformId: Id> Debug for Uniform<ProgramId, UniformId>

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

Formats the value using the given formatter.

impl From<&Uniform<String, String>> for UniformJs

fn from(js_uniform_inner: &UniformJsInner) -> Self

Converts to this type from the input type.

impl From<Uniform<String, String>> for JsValue

fn from(uniform: UniformJsInner) -> Self

Converts to this type from the input type.

impl From<Uniform<String, String>> for UniformJs

fn from(js_uniform_inner: UniformJsInner) -> Self

Converts to this type from the input type.

impl<ProgramId: Id, UniformId: Id> Hash for Uniform<ProgramId, UniformId>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<ProgramId: Id, UniformId: Id> PartialEq for Uniform<ProgramId, UniformId>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
