Struct DeviceCatalog 

pub struct DeviceCatalog { /* private fields */ }

Registry of stream-device providers.

Implementations

impl DeviceCatalog

pub fn new() -> Self

Builds an empty device catalog.

pub fn default_modeled() -> Self

Builds a catalog with deterministic modeled MIDI and audio providers.

pub fn with_registry_audio_devices(registry: &Registry) -> Self

Builds a modeled catalog plus audio devices exported by loaded libs.

pub fn register(&mut self, provider: Box<dyn DeviceProvider>)

Registers a device provider.

pub fn register_provider_sites(&mut self, router: &AudioRouter)

Adds a snapshot of the audio sites currently registered by a provider.

pub fn register_registry_audio_devices(&mut self, registry: &Registry)

Adds audio-device records currently owned by loaded registry libs.

pub fn enumerate(&self) -> Result<Vec<DeviceRecord>>

Enumerates every registered provider.

pub fn open(&self, id: &Symbol) -> Result<Box<dyn StreamEvalSite>>

Opens a cataloged stream evaluation site by device id.

pub fn open_live(&self, id: &Symbol) -> Result<MidiLiveEvalSite>

Opens a cataloged MIDI device as a live MIDI evaluation site.

pub fn enumerate_midi(&self) -> Result<Vec<DeviceRecord>>

Enumerates MIDI device rows.

pub fn enumerate_audio(&self) -> Result<Vec<DeviceRecord>>

Enumerates audio device rows.

pub fn audio_backend_names(&self) -> Result<Vec<String>>

Returns safe audio backend candidate names from catalog records.

Hardware records contribute their transport name. Modeled records keep the deterministic modeled fallback as the final candidate.

pub fn midi_backend_names(&self) -> Result<Vec<String>>

Returns safe MIDI backend candidate names from catalog records.

Hardware records contribute their transport name. Modeled records keep the deterministic modeled fallback as the final candidate.

Trait Implementations

impl Default for DeviceCatalog

fn default() -> Self

Returns the “default value” for a type.
