//! Iced Audio is an extension to the [`Iced`] GUI library with useful widgets //! for audio applications such as VST / LV2 plugins. //! //! # Installation //! //! Add `iced` and `iced_audio` as dependencies in your `Cargo.toml`: //! //! ``` //! iced = { version = "0.1", features = ["image"] } //! iced_audio = "0.3" //! ``` //! //! This crate is currently experimental and incomplete. Master branch moves //! fast and may contain breaking changes! //! //! # Simple Usage Example //! //! This crate assumes you know the basics of how to use [`Iced`]. If you //! haven't alreay, please check it out [`here`]. //! //! ``` //! // Import iced modules. //! use iced::{ //! Align, Column, Container, Element, Length, Sandbox, Settings, Text, //! }; //! // Import iced_audio modules. //! use iced_audio::{ //! h_slider, knob, v_slider, xy_pad, DBRange, FloatRange, FreqRange, HSlider, //! IntRange, Knob, TickMark, TickMarkGroup, TickMarkTier, VSlider, XYPad, //! }; //! //! // Create a unique identifier for each parameter. Note you may also use any //! // type you want such as u32, i32, Strings, etc. //! #[derive(Debug, Copy, Clone)] //! pub enum ParamID { //! HSliderInt, //! VSliderDB, //! KnobFreq, //!
