Struct PortMeta 

pub struct PortMeta {
    pub direction: PortDir,
    pub channels: u16,
    pub sample_format: SampleFmt,
}

Available on crate feature topology only.

Serializable mirror of audio_core_bsd::PortDescriptor.

Stores the three fields needed to describe a port’s contract: its direction, channel count, and sample format. Convert to/from a PortDescriptor with PortMeta::from_descriptor / PortMeta::to_descriptor.

Fields

direction: PortDir

Whether this port is an input or output.

channels: u16

Number of channels carried by the port.

sample_format: SampleFmt

Numeric format of each sample.

Implementations

impl PortMeta

pub fn from_descriptor(d: PortDescriptor) -> Self

Constructs a PortMeta from an audio-core-bsd PortDescriptor.

This is a lossless field-by-field mapping; the reverse conversion is PortMeta::to_descriptor.

pub fn to_descriptor(self) -> PortDescriptor

Converts this PortMeta back into an audio-core-bsd PortDescriptor.
