Struct IndexBufferAny

Source
pub struct IndexBufferAny { /* private fields */ }
Expand description

An IndexBuffer without any type information.

Makes it easier to store in a Vec or return from a function, for example.

Implementations§

Source§

impl IndexBufferAny

Source

pub fn get_primitives_type(&self) -> PrimitiveType

Returns the type of primitives associated with this index buffer.

Source

pub fn get_indices_type(&self) -> IndexType

Returns the data type of the indices inside this index buffer.

Methods from Deref<Target = BufferAny>§

Source

pub fn as_slice_any(&self) -> BufferAnySlice<'_>

Builds a slice-any containing the whole subbuffer.

Source

pub unsafe fn as_typed_slice_mut<T>(&mut self) -> BufferMutSlice<'_, T>
where T: Content + ?Sized,

Builds a mutable typed slice containing the whole subbuffer, without checking the type.

Source

pub unsafe fn as_typed_slice<T>(&self) -> BufferSlice<'_, T>
where T: Content + ?Sized,

Builds a typed slice containing the whole subbuffer, without checking the type.

Source

pub fn get_elements_size(&self) -> usize

Returns the size in bytes of each element in the buffer.

Source

pub fn get_elements_count(&self) -> usize

Returns the number of elements in the buffer.

Source

pub fn get_context(&self) -> &Rc<Context>

Returns the context corresponding to this buffer.

Source

pub fn get_size(&self) -> usize

Returns the number of bytes in this subbuffer.

Source

pub fn invalidate(&self)

Invalidates the content of the buffer. The data becomes undefined.

This operation is a no-op if the backend doesn’t support it and for persistent-mapped buffers.

Source

pub unsafe fn read<T>(&self) -> Result<<T as Content>::Owned, ReadError>
where T: Content,

UNSTABLE. This function can be removed at any moment without any further notice.

Considers that the buffer is filled with elements of type T and reads them.

§Panic

Panics if the size of the buffer is not a multiple of the size of the data. For example, trying to read some (u8, u8, u8, u8)s from a buffer of 7 bytes will panic.
