Expand description

Internal format of a texture.

The actual format of a texture is not necessarily one of the predefined ones, so we have to use a very generic description.

Implementations§

source §

impl InternalFormat

source

pub fn get_total_bits(&self) -> usize

Returns the total number of bits of this format.

Trait Implementations§

source §

impl Clone for InternalFormat

source §

fn clone(&self) -> InternalFormat

Returns a copy of the value. Read more

1.0.0 · source§

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

Performs copy-assignment from source. Read more

source §

impl Debug for InternalFormat

source §

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

Formats the value using the given formatter. Read more

source §

impl PartialEq for InternalFormat

source §

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

This method tests for self and other values to be equal, and is used by ==.

1.0.0 · source§

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

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

Blanket Implementations§

source §

impl<T> Any for T
where T: 'static + ?Sized,

source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source §

impl<T> Borrow<T> for T
where T: ?Sized,

source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

source §

impl<T> BorrowMut<T> for T
where T: ?Sized,

source §

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

source §

impl<T> Content for T
where T: Copy,

§

type Owned = T

A type that holds a sized version of the content.

source §

unsafe fn read<F, E>(size: usize, f: F) -> Result<T, E>
where F: FnOnce(&mut T) -> Result<(), E>,

Prepares an output buffer, then turns this buffer into an Owned. User-provided closure F must only write to and not read from &mut Self.

source §

fn get_elements_size() -> usize

Returns the size of each element.

source §

fn to_void_ptr(&self) -> *const ()

Produces a pointer to the data.

source §

fn ref_from_ptr<'a>(ptr: mut (), size: usize) -> Option<mut T>

Builds a pointer to this type from a raw pointer.

source §

fn is_size_suitable(size: usize) -> bool

Returns true if the size is suitable to store a type like this.

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

§

impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
