Struct SampleBody 

pub struct SampleBody {
    pub pcm: Vec<i8>,
    pub loop_start: u32,
    pub loop_length: u32,
    pub volume: u8,
    pub finetune: i8,
}

Per-sample decoded body plus the loop metadata needed by the mixer.

Fields

pcm: Vec<i8>

Raw signed 8-bit PCM. Empty if the header declared zero length.

loop_start: u32

Loop start in samples (0 if sample does not loop).

loop_length: u32

Loop length in samples (0 if sample does not loop — spec says repeat length of 2 also means “no loop”).

volume: u8

Default volume 0..=64.

finetune: i8

Finetune -8..=7.

Implementations

impl SampleBody

pub fn is_looped(&self) -> bool

True if this sample has a valid loop region.

Trait Implementations

impl Clone for SampleBody

fn clone(&self) -> SampleBody

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SampleBody

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SampleBody

fn default() -> SampleBody

Returns the “default value” for a type.

impl SampleSource for SampleBody

fn len(&self) -> usize

Total number of PCM frames.

fn loop_start(&self) -> usize

Loop start index (frames).

fn loop_end(&self) -> usize

Loop end index (frames), exclusive.

fn loop_kind(&self) -> LoopKind

Loop mode.

fn at(&self, idx: usize) -> f32

Sample at integer index, normalised to -1.0..=1.0. Callers are responsible for ensuring idx < len(); implementations may return 0.0 for out-of-range indices defensively.

fn is_empty(&self) -> bool

True if this sample has no PCM data.
