Struct ImageId 

pub struct ImageId(pub u32);

Opaque handle to a backend-registered image.

Returned by RenderBackend::register_image; passed to RenderBackend::draw_image. Valid until unregister_image or the backend is dropped. Two backends do not share ids - ids from one backend must not be used with another.

Tuple Fields

0: u32

Implementations

impl ImageId

pub const INVALID: ImageId

Sentinel value returned by the default trait impls when a backend does not override register_image.

Trait Implementations

impl Clone for ImageId

fn clone(&self) -> ImageId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageId

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

Formats the value using the given formatter.

impl Hash for ImageId

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

where __H: Hasher,

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 PartialEq for ImageId

fn eq(&self, other: &ImageId) -> 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.
