Trait for scalar sample values used in image processing.

Implemented for u8, u16, and f32 — the common pixel sample types in raw image processing pipelines.

Required Associated Constants

const MAX: Self

The maximum representable value for this sample type.

const MIN: Self

The minimum representable value for this sample type.

const BIT_DEPTH: u8

The number of bits used to represent this sample.

Required Methods

fn clamp_sample(self) -> Self

Clamp a value to the valid range.

fn from_normalized(v: f32) -> Self

Convert from a normalized f32 value in [0.0, 1.0] to this sample type.

fn to_normalized(self) -> f32

Convert this sample to a normalized f32 value in [0.0, 1.0].

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
