Module glium::buffer

A buffer is a memory location accessible to the video card.

The purpose of buffers is to serve as a space where the GPU can read from or write data to. It can contain a list of vertices, indices, uniform data, etc.

Buffers management in glium

There are three levels of abstraction in glium:

• A Buffer corresponds to an OpenGL buffer object. This type is not public.
• A BufferView corresponds to a part of a Buffer. One buffer can contain one or multiple subbuffers.
• The VertexBuffer, IndexBuffer, UniformBuffer, PixelBuffer, ... types are abstractions over a subbuffer indicating their specific purpose. They implement Deref for the subbuffer. These types are in the vertex, index, ... modules.

Structs

BufferView	Represents a view of a buffer.
BufferViewAny	Represents a sub-part of a buffer.
BufferViewAnySlice	Slice of a BufferView without any type info.
BufferViewMutSlice	Represents a sub-part of a buffer.
BufferViewSlice	Represents a sub-part of a buffer.
Inserter	Allows inserting a fence in the list.
Mapping	A mapping of a buffer for reading and writing.
ReadMapping	A mapping of a buffer for reading.
WriteMapping	A mapping of a buffer for write only.

Enums

BufferCreationError	Error that can happen when creating a buffer.
BufferMode	How the buffer is created.
ReadError	Error that can happen when reading from a buffer.

Traits

Content

Trait for types of data that can be put inside buffers.

Functions

is_buffer_read_supported

Returns true if reading from a buffer is supported by the backend.
