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](https://www.alsa-project.org/alsa-doc/alsa-lib/) +//! can be consulted for additional information. +//! +//!
