Trait abstracting a pixel sample type for JPEG-LS encoding/decoding.

Required Associated Constants

const MAX_VAL_DEFAULT: i32

The maximum sample value (e.g. 255 for 8-bit, 65535 for 16-bit).

const BYTES: usize

Number of bytes per sample.

Required Methods

fn from_i32_clamped(val: i32, max_val: i32) -> Self

Convert from an i32, clamping to [0, max_val].

fn read_le(data: &[u8], offset: usize) -> Self

Read a sample from a byte slice in native (little-endian) order.

fn write_le(data: &mut [u8], offset: usize, val: Self)

Write a sample to a byte slice in native (little-endian) order.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
