Struct AlsaPcmName 

pub struct AlsaPcmName { /* private fields */ }

Parsed ALSA PCM name accepted by this adapter.

Implementations

impl AlsaPcmName

pub fn parse(raw: impl Into<String>) -> Result<Self>

Parses an ALSA PCM name, accepting default, hw:*, and plughw:*.

The hw:* and plughw:* tails must be non-empty and whitespace-free. Any other name is rejected with an Error::Eval.

Examples

use sim_lib_stream_alsa::{AlsaPcmName, AlsaPcmNameKind};

let name = AlsaPcmName::parse("plughw:1,0").unwrap();
assert_eq!(name.kind(), AlsaPcmNameKind::PlugHw);
assert_eq!(name.raw(), "plughw:1,0");
assert!(!name.is_default());
assert!(AlsaPcmName::parse("oss:0").is_err());

pub fn raw(&self) -> &str

Returns the original PCM name string as parsed.

pub fn kind(&self) -> AlsaPcmNameKind

Returns the parsed name family.

pub fn is_default(&self) -> bool

Returns true when this is the ALSA default PCM.

pub fn device_symbol(&self, direction: HostDirection) -> Symbol

Builds the SIM device Symbol for this PCM name in the given direction, of the form alsa/<raw>/<role> where the role suffix is capture, playback, or duplex.

Trait Implementations

impl Clone for AlsaPcmName

fn clone(&self) -> AlsaPcmName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Eq for AlsaPcmName

impl PartialEq for AlsaPcmName

fn eq(&self, other: &AlsaPcmName) -> 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.
