Struct AudioBlockSequentialViewMut 

pub struct AudioBlockSequentialViewMut<'a, S>
where
    S: Sample,
{ /* private fields */ }

A mutable view of sequential audio data.

• Layout: [ch0, ch0, ch0, ch1, ch1, ch1]
• Interpretation: All samples from ch0 are stored first, followed by all from ch1, etc.
• Terminology: Described as “channels first” in the sense that all data for one channel appears before any data for the next.
• Usage: Used in DSP pipelines where per-channel processing is easier and more efficient.

Example

use audio_blocks::*;

let mut data = vec![0.0, 0.0, 0.0, 1.0, 1.0, 1.0];

let block = AudioBlockSequentialViewMut::from_slice(&mut data, 2, 3);

assert_eq!(block.channel(0), &[0.0, 0.0, 0.0]);
assert_eq!(block.channel(1), &[1.0, 1.0, 1.0]);

Implementations

impl<'a, S> AudioBlockSequentialViewMut<'a, S>

where S: Sample,

pub fn from_slice( data: &'a mut [S], num_channels: u16, num_frames: usize, ) -> AudioBlockSequentialViewMut<'a, S>

Creates a new audio block from a mutable slice of sequential audio data.

Parameters

• data - The mutable slice containing sequential audio samples
• num_channels - Number of audio channels in the data
• num_frames - Number of audio frames in the data

Panics

Panics if the length of data doesn’t equal num_channels * num_frames.

pub fn from_slice_limited( data: &'a mut [S], num_channels_visible: u16, num_frames_visible: usize, num_channels_available: u16, num_frames_available: usize, ) -> AudioBlockSequentialViewMut<'a, S>

Creates a new audio block from a mutable slice with limited visibility.

This function allows creating a view that exposes only a subset of the allocated channels and frames, which is useful for working with a logical section of a larger buffer.

Parameters

• data - The mutable slice containing sequential audio samples
• num_channels_visible - Number of audio channels to expose in the view
• num_frames_visible - Number of audio frames to expose in the view
• num_channels_allocated - Total number of channels allocated in the data buffer
• num_frames_allocated - Total number of frames allocated in the data buffer

Panics

• Panics if the length of data doesn’t equal num_channels_allocated * num_frames_allocated
• Panics if num_channels_visible exceeds num_channels_allocated
• Panics if num_frames_visible exceeds num_frames_allocated

pub unsafe fn from_ptr( ptr: *mut S, num_channels: u16, num_frames: usize, ) -> AudioBlockSequentialViewMut<'a, S>

Creates a new audio block from a pointer.

Safety

The caller must ensure that:

• ptr points to valid memory containing at least num_channels_available * num_frames_available elements
• The memory referenced by ptr must be valid for the lifetime of the returned SequentialView
• The memory must not be mutated through other pointers while this view exists

pub unsafe fn from_ptr_limited( ptr: *mut S, num_channels_visible: u16, num_frames_visible: usize, num_channels_allocated: u16, num_frames_allocated: usize, ) -> AudioBlockSequentialViewMut<'a, S>

Creates a new audio block from a pointer with a limited amount of channels and/or frames.

Safety

The caller must ensure that:

• ptr points to valid memory containing at least num_channels_available * num_frames_available elements
• The memory referenced by ptr must be valid for the lifetime of the returned SequentialView
• The memory must not be mutated through other pointers while this view exists
