Struct ContextId 

pub struct ContextId<T: Texture>(/* private fields */);

Identifies a renderer context for a specific texture type.

Renderers with the same ContextId are assumed to be texture-compatible, meaning textures created by one can be imported into another.

Implementations

impl<T: Texture> ContextId<T>

pub fn new() -> Self

Allocates a new ContextId.

pub fn map<Tex: Texture>(self) -> ContextId<Tex>

Maps this ContextId to one with another Texture type.

This is typically used by wrapper or derivative renderers that define a new TextureId while reusing the underlying context for rendering.

pub fn erased(&self) -> ErasedContextId

where T: 'static,

Returns an ErasedContextId representing this context without the texture type.

This is useful when storing or comparing contexts across different texture types.

Trait Implementations

impl<T: Texture> Clone for ContextId<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Texture> Debug for ContextId<T>

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

Formats the value using the given formatter.

impl<T: Texture> Default for ContextId<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Texture> Hash for ContextId<T>

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<T: Texture> Ord for ContextId<T>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: Texture> PartialEq for ContextId<T>

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.

impl<T: Texture> PartialOrd for ContextId<T>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
