Trait AudioSource 

pub trait AudioSource: Send {
    // Required methods
    fn channels(&self) -> u16;
    fn sample_rate(&self) -> u32;
    fn duration(&self) -> Option<f64>;

}

A decoded audio stream.

Required Methods

fn channels(&self) -> u16

Channels in each block’s frames.

fn sample_rate(&self) -> u32

Frames per second.

fn duration(&self) -> Option<f64>

The stream’s length in seconds, when the file says.

fn next_block(&mut self) -> Option<Block<'_>>

The next block of samples, or None at the end.

fn seek(&mut self, secs: f64) -> Result<f64, AudioError>

Moves so the next block starts at secs (clamped to the stream) and returns the time it starts at.

fn position(&self) -> f64

Where the next block starts, in seconds.

fn backend(&self) -> &'static str

Which decoder backs the stream, for messages and tests.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
