Struct StmSampleBody 

pub struct StmSampleBody {
    pub pcm: Vec<i8>,
    pub loop_start: u16,
    pub loop_end: u16,
    pub volume: u8,
    pub c3_hz: u16,
}

Per-instrument sample body after extraction.

Fields

pcm: Vec<i8>

Raw signed 8-bit PCM. Empty if the instrument has no samples or the file was truncated.

loop_start: u16

loop_end: u16

volume: u8

c3_hz: u16

Implementations

impl StmSampleBody

pub fn is_looped(&self) -> bool

True if this body carries a valid forward loop. STM signals “no loop” either with loop_end == 0xFFFF or by having loop_end <= loop_start.

Trait Implementations

impl Clone for StmSampleBody

fn clone(&self) -> StmSampleBody

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StmSampleBody

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

Formats the value using the given formatter.

impl Default for StmSampleBody

fn default() -> StmSampleBody

Returns the “default value” for a type.

impl SampleSource for StmSampleBody

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.
