PNMixer-rs is a mixer for the system tray.

+ +

Design Overview

+

The lowest level part of the code is the sound backend. Only Alsa is supported +at the moment, but more backends may be added in the future.

+ +

The backend is hidden behind a frontend, defined in audio.rs. Only audio.rs +deals with audio backends. This means that the whole of the code is blissfully +ignorant of the audio backend in use.

+ +

audio.rs is also in charge of emitting signals whenever a change happens. +This means that PNMixer-rs design is quite signal-oriented, so to say.

+ +

The ui code is nothing fancy. Each ui element...

+ + + +

There's something you should keep in mind. Audio on a computer is a shared +resource. PNMixer-rs isn't the only one that can change it. At any moment the +audio volume may be modified by someone else, and we must update the ui +accordingly. So listening to changes from the audio subsystem (and therefore +having a signal-oriented design) is the most obvious solution to solve that +problem.

+//! PNMixer-rs is a mixer for the system tray.
+//!
+//! # Design Overview
+//!
+//! The lowest level part of the code is the sound backend. Only Alsa is supported
+//! at the moment, but more backends may be added in the future.
+//!
+//! The backend is hidden behind a frontend, defined in `audio.rs`. Only `audio.rs`
+//! deals with audio backends. This means that the whole of the code is blissfully
+//! ignorant of the audio backend in use.
+//!
+//! `audio.rs` is also in charge of emitting signals whenever a change happens.
+//! This means that PNMixer-rs design is quite signal-oriented, so to say.
+//!
+//! The ui code is nothing fancy. Each ui element...
+//!
+//! * is defined in a single file
+//! * strives to be standalone
+//! * accesses the sound system with function calls
+//! * listens to signals from the audio subsystem to update its appearance
+//!
+//! There's something you should keep in mind. Audio on a computer is a shared
+//! resource. PNMixer-rs isn't the only one that can change it. At any moment the
+//! audio volume may be modified by someone else, and we must update the ui
+//! accordingly. So listening to changes from the audio subsystem (and therefore
+//! having a signal-oriented design) is the most obvious solution to solve that
+//! problem.
