Struct glium::buffer::BufferViewMutSlice [−] [src]

pub struct BufferViewMutSlice<'a, T: ?Sized> where T: Content {
    // some fields omitted
}

Represents a sub-part of a buffer.

Methods

`impl<'a, T: ?Sized> BufferViewMutSlice<'a, T> where T: Content`

`fn get_size(&self) -> usize`

Returns the size in bytes of this slice.

`fn map(self) -> Mapping<'a, T>`

Maps the buffer in memory for both reading and writing.

`fn map_read(self) -> ReadMapping<'a, T>`

Maps the buffer in memory for reading.

`fn map_write(self) -> WriteMapping<'a, T>`

Maps the buffer in memory for writing only.

`fn write(&self, data: &T)`

Uploads some data in this buffer.

Panic

Panics if the length of data is different from the length of this buffer.

`fn invalidate(&self)`

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

This operation is a no-op if the backend doesn't support it.

`fn read(&self) -> Result<T, ReadError>`

Reads the content of the buffer.

`fn as_slice_any(self) -> BufferViewAnySlice<'a>`

Builds a slice-any containing the whole subbuffer.

`impl<'a, T> BufferViewMutSlice<'a, [T]> where [T]: Content, T: Copy + 'a`

`fn len(&self) -> usize`

Returns the number of elements in this slice.

`fn slice(self, range: Range<usize>) -> Option<BufferViewMutSlice<'a, [T]>>`

Builds a subslice of this slice. Returns None if out of range.

`impl<'a, T> BufferViewMutSlice<'a, [T]> where T: PixelValue + 'a`

`fn read_as_texture_1d<S>(&self) -> Result<S, ReadError> where S: Texture1dDataSink<T>`
