Fields§
§label: Option<&'a str>
Debug label of a buffer. This will show up in graphics debuggers for easy identification.
size: u64
Size of a buffer, in bytes.
usage: BufferUsages
Usages of a buffer. If the buffer is used in any way that isn’t specified here, the operation will panic.
Specifying only usages the application will actually perform may increase performance.
Additionally, on the WebGL backend, there are restrictions on [BufferUsages::INDEX
];
see [DownlevelFlags::UNRESTRICTED_INDEX_BUFFER
] for more information.
mapped_at_creation: bool
Allows a buffer to be mapped immediately after they are made. It does not have to be [BufferUsages::MAP_READ
] or
[BufferUsages::MAP_WRITE
], all buffers are allowed to be mapped at creation.
If this is true
, size
must be a multiple of
[COPY_BUFFER_ALIGNMENT
].
