fuchsia_audio::vmo_buffer

Struct VmoBuffer

Source 
pub struct VmoBuffer { /* private fields */ }
Expand description

A VMO-backed ring buffer that contains frames of audio.

Implementations§

Source§

impl VmoBuffer

Source

pub fn new( vmo: Vmo, num_frames: u64, format: Format, ) -> Result<Self, VmoBufferError>

Source

pub fn data_size_bytes(&self) -> u64

Returns the size of the buffer in bytes.

This may be less than the size of the backing VMO.

Source

pub fn write_to_frame( &self, frame: u64, buf: &[u8], ) -> Result<(), VmoBufferError>

Writes all frames from buf to the ring buffer at position frame.

Source

pub fn read_from_frame( &self, frame: u64, buf: &mut [u8], ) -> Result<(), VmoBufferError>

Reads frames from the ring buffer into buf starting at position frame.
