Struct StreamSpec 

pub struct StreamSpec { /* private fields */ }

A declarative description of one stream on a device.

The framework turns a StreamSpec into an kAudioStreamClassID audio object, answers the HAL’s property queries about it (direction, starting channel, virtual format), and routes the stream’s samples into Driver::process_io. Build one with StreamSpec::input / StreamSpec::output and the builder-style setters.

Implementations

impl StreamSpec

pub const fn input(format: StreamFormat) -> Self

An input stream carrying format, starting at channel 1.

pub const fn output(format: StreamFormat) -> Self

An output stream carrying format, starting at channel 1.

pub const fn with_starting_channel(self, channel: u32) -> Self

Builder-style: set the 1-based channel this stream’s first channel maps to within the owning device.

pub const fn with_format(self, format: StreamFormat) -> Self

Builder-style: replace the stream format.

pub const fn direction(&self) -> StreamDirection

The direction this stream carries audio.

pub const fn starting_channel(&self) -> u32

The 1-based starting channel (kAudioStreamPropertyStartingChannel).

pub const fn format(&self) -> StreamFormat

The stream’s StreamFormat (kAudioStreamPropertyVirtualFormat).

pub const fn channels(&self) -> u32

The stream’s channel count, taken from its format.

Trait Implementations

impl Clone for StreamSpec

fn clone(&self) -> StreamSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamSpec

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

Formats the value using the given formatter.

impl PartialEq for StreamSpec

fn eq(&self, other: &StreamSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
