Trait framing::AsBytes
[−]
[src]
pub unsafe trait AsBytes: Sized { type Bytes: AsRef<[u8]> + AsMut<[u8]> + Default + From<Self> + Into<Self>; fn width() -> usize; }
Describes a kind of pixel that is made up of a fixed number of bytes.
Safety
Perfectly safe to implement as long as the length of the byte array is
always equal to Self::width(). When the bugs in associated constants are
ironed out this will hopefully use them, and be safe to implement.
Associated Types
type Bytes: AsRef<[u8]> + AsMut<[u8]> + Default + From<Self> + Into<Self>
The type that represents the collection of bytes.
Unless you know better, this type should probably be [u8; N], where
N is the number of bytes in each pixel.
Required Methods
fn width() -> usize
The number of channels in each pixel.
For example, RGB might have three bytes per pixel, and RGBA might
have four channels per pixel. This should match the length of the
Bytes type, unless you enjoy breaking perfectly good code.
