Struct AudioPipe

struct AudioPipe {
    path: String,
    stream: usize,
    channels: u32,
    duration: f64,
    child: Option<(Child, ChildStdout)>,
    buf: Vec<f32>,
    pos: usize,
    bytes: Vec<u8>,
    next: i64,
    end: i64,
}

Fields

path: String

stream: usize

channels: u32

duration: f64

child: Option<(Child, ChildStdout)>

buf: Vec<f32>

Decoded interleaved stereo; buf[pos..] is unread.

pos: usize

bytes: Vec<u8>

next: i64

Absolute sample-frame index of buf[pos].

end: i64

Frame index at which the pipe hit EOF (i64::MAX = unknown).

Implementations

impl AudioPipe

fn respawn(&mut self, frame: i64) -> bool

fn refill(&mut self) -> bool

Refill buf from the pipe. False at EOF.

Trait Implementations

impl AudioSource for AudioPipe

fn duration(&self) -> f64

fn read_at(&mut self, t: f64, out: &mut [f32])

Fill out (interleaved stereo f32 @ SAMPLE_RATE, frames = out.len()/2) starting at source time t. Zero-fill past the end. Must be cheap for sequential calls (t advancing by exactly the previous block).

impl Drop for AudioPipe

fn drop(&mut self)

Executes the destructor for this type.
