Trait audio_core::ExactSizeBuf[−][src]

pub trait ExactSizeBuf: Buf {
    fn frames(&self) -> usize;
}

Trait used to describe a buffer that knows exactly how many frames it has regardless of if it’s sized or not.

Examples

use audio::ExactSizeBuf;

fn test<T>(buf: T) where T: ExactSizeBuf {
    assert_eq!(buf.frames(), 4);
}

test(audio::interleaved![[0i16; 4]; 4]);
test(audio::sequential![[0i16; 4]; 4]);
test(audio::dynamic![[0i16; 4]; 4]);
test(audio::wrap::interleaved([0i16; 16], 4));
test(audio::wrap::sequential([0i16; 16], 4));

Required methods

`fn frames(&self) -> usize`[src]

The number of frames in a buffer.

Examples

use audio::ExactSizeBuf;

fn test<T>(buf: T) where T: ExactSizeBuf {
    assert_eq!(buf.frames(), 4);
}

test(audio::interleaved![[0i16; 4]; 4]);
test(audio::sequential![[0i16; 4]; 4]);
test(audio::dynamic![[0i16; 4]; 4]);
test(audio::wrap::interleaved([0i16; 16], 4));
test(audio::wrap::sequential([0i16; 16], 4));
