Trait gbm::ReadableMappedBufferObject [−] [src]

pub trait ReadableMappedBufferObject<'a> {
    fn stride(&self) -> u32;
    fn x(&self) -> u32;
    fn y(&self) -> u32;
    fn height(&self) -> u32;
    fn width(&self) -> u32;
    fn buffer(&'a self) -> &'a [u8];
}

Common functionality for all mapped buffer objects

Required Methods

`fn stride(&self) -> u32`

Get the stride of the buffer object

This is calculated by the backend when it does the allocation of the buffer.

`fn x(&self) -> u32`

The X (top left origin) starting position of the mapped region for the buffer

`fn y(&self) -> u32`

The Y (top left origin) starting position of the mapped region for the buffer

`fn height(&self) -> u32`

The height of the mapped region for the buffer

`fn width(&self) -> u32`

The width of the mapped region for the buffer

`fn buffer(&'a self) -> &'a [u8]`

Access to the underlying image buffer
