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§

impl InternalFormat

pub fn get_total_bits(&self) -> usize

Returns the total number of bits of this format.

Trait Implementations§

impl Clone for InternalFormat

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

impl Debug for InternalFormat

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

Formats the value using the given formatter. Read more

impl PartialEq<InternalFormat> for InternalFormat

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§

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

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

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

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

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

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

Mutably borrows from an owned value. Read more

impl<T> Content for Twhere T: Copy,

type Owned = T

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

Produces a pointer to the data.

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

Builds a pointer to this type from a raw pointer.

fn is_size_suitable(size: usize) -> bool

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

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into<U> for Twhere U: From<T>,
