Trait BytesSample 

pub trait BytesSample {
    type NumericType: Copy;

    const BYTES_PER_SAMPLE: usize;

    // Required methods
    fn from_slice(bytes: &[u8]) -> Self;
    fn as_slice(&self) -> &[u8] ;

    fn from_number(value: Self::NumericType) -> Self;
}

A trait for converting samples stored as raw bytes into a numerical type. Each implementation defines the associated type NumericType, which is the nearest matching numeric type for the original format. If a direct match exists, this is used. For example signed 16 bit integer samples use i16. For formats that don’t have a direct match, the next larger numeric type is used. For example for 24 bit signed integers, this means i32. The values are scaled to use the full range of the NumericType associated type.

Required Associated Constants

const BYTES_PER_SAMPLE: usize

The number of bytes making up each sample value.

Required Associated Types

type NumericType: Copy

The closest matching numeric type.

Required Methods

fn from_slice(bytes: &[u8]) -> Self

Create a new ByteSample from a slice of raw bytes. The slice length must be at least the number of bytes for a sample value.

fn as_slice(&self) -> &[u8]

Return the raw bytes as a slice.

fn as_mut_slice(&mut self) -> &mut [u8]

Return the raw bytes as a mutable slice.

fn to_number(&self) -> Self::NumericType

Convert the raw bytes to a numerical value.

fn from_number(value: Self::NumericType) -> Self

Convert a numerical value to raw bytes.

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.
