Crate alsa [−] [src]

Thin but safe wrappers for ALSA.

This ALSA API wrapper/binding is WIP - the ALSA API is huge, and new functions and structs might be added as requested.

Most functions map 1-to-1 to alsa-lib functions, e g, ctl::CardInfo::get_id() is a wrapper around snd_ctl_card_info_get_id and the alsa-lib documentation can be consulted for additional information.

Enjoy!

Modules

card	Sound card enumeration
ctl	Control device API
device_name	Enumerate devices in the alsa library configuration
hctl	HCtl API - for mixer control and jack detection
mixer	Mixer API - Simple Mixer API for mixer control
pcm	Audio playback and capture
poll	Tiny poll ffi
rawmidi	MIDI devices I/O and enumeration
seq	MIDI sequencer I/O and enumeration

Structs

Ctl	snd_ctl_t wrapper
Error	Most ALSA functions can return a negative error code. If so, then that error code is wrapped into this `Error` struct. An Error is also returned in case ALSA returns a string that cannot be translated into Rust's UTF-8 strings.
Output	snd_output_t wrapper

Enums

Direction	Replaces constants ending with PLAYBACK/CAPTURE as well as INPUT/OUTPUT
Round	Rounding mode (used in some mixer related calls)
ValueOr	Used to restrict hw parameters. In case the submitted value is unavailable, in which direction should one search for available values?
