Implement full SSD1306 OLED display support: - Splash screen on boot (1.5s) with project name, version, board - Dashboard showing radio state, config, counters, RSSI/SNR - RSSI history sparkline (64-sample ring buffer, 2px-wide bars) - DisplayOn/DisplayOff host commands routed via dedicated channel - Pure render functions against generic DrawTarget (no hardware coupling) - Display on/off control bypasses radio task entirely Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

//! # Documentation for Additional Attributes

|
|
//! ## Attributes on Enums
|
|
//!
|
|
//! Strum supports several custom attributes to modify the generated code. At the enum level, the following attributes are supported:
|
|
//!
|
|
//! - `#[strum(serialize_all = "case_style")]` attribute can be used to change the case used when serializing to and deserializing
|
|
//! from strings. This feature is enabled by [withoutboats/heck](https://github.com/withoutboats/heck) and supported case styles are:
|
|
//!
|
|
//! - `camelCase`
|
|
//! - `PascalCase`
|
|
//! - `kebab-case`
|
|
//! - `snake_case`
|
|
//! - `SCREAMING_SNAKE_CASE`
|
|
//! - `SCREAMING-KEBAB-CASE`
|
|
//! - `lowercase`
|
|
//! - `UPPERCASE`
|
|
//! - `title_case`
|
|
//! - `mixed_case`
|
|
//! - `Train-Case`
|
|
//!
|
|
//! ```rust
|
|
//! use strum_macros;
|
|
//!
|
|
//! #[derive(Debug, Eq, PartialEq, strum_macros::Display)]
|
|
//! #[strum(serialize_all = "snake_case")]
|
|
//! enum Brightness {
|
|
//! DarkBlack,
|
|
//! Dim {
|
|
//! glow: usize,
|
|
//! },
|
|
//! #[strum(serialize = "bright")]
|
|
//! BrightWhite,
|
|
//! }
|
|
//!
|
|
//! assert_eq!(
|
|
//! String::from("dark_black"),
|
|
//! Brightness::DarkBlack.to_string().as_ref()
|
|
//! );
|
|
//! assert_eq!(
|
|
//! String::from("dim"),
|
|
//! Brightness::Dim { glow: 0 }.to_string().as_ref()
|
|
//! );
|
|
//! assert_eq!(
|
|
//! String::from("bright"),
|
|
//! Brightness::BrightWhite.to_string().as_ref()
|
|
//! );
|
|
//! ```
|
|
//!
|
|
//! - You can also apply the `#[strum(ascii_case_insensitive)]` attribute to the enum,
|
|
//! and this has the same effect of applying it to every variant.
|
|
//!
|
|
//! ## Attributes on Variants
|
|
//!
|
|
//! Custom attributes are applied to a variant by adding `#[strum(parameter="value")]` to the variant.
|
|
//!
|
|
//! - `serialize="..."`: Changes the text that `FromStr()` looks for when parsing a string. This attribute can
|
|
//! be applied multiple times to an element and the enum variant will be parsed if any of them match.
|
|
//!
|
|
//! - `to_string="..."`: Similar to `serialize`. This value will be included when using `FromStr()`. More importantly,
|
|
//! this specifies what text to use when calling `variant.to_string()` with the `Display` derivation, or when calling `variant.as_ref()` with `AsRefStr`.
|
|
//!
|
|
//! - `default`: Applied to a single variant of an enum. The variant must be a Tuple-like
|
|
//! variant with a single piece of data that can be create from a `&str` i.e. `T: From<&str>`.
|
|
//! The generated code will now return the variant with the input string captured as shown below
|
|
//! instead of failing.
|
|
//!
|
|
//! ```text
|
|
//! // Replaces this:
|
|
//! _ => Err(strum::ParseError::VariantNotFound)
|
|
//! // With this in generated code:
|
|
//! default => Ok(Variant(default.into()))
|
|
//! ```
|
|
//! The plugin will fail if the data doesn't implement From<&str>. You can only have one `default`
|
|
//! on your enum.
|
|
//!
|
|
//! - `disabled`: removes variant from generated code.
|
|
//!
|
|
//! - `ascii_case_insensitive`: makes the comparison to this variant case insensitive (ASCII only).
|
|
//! If the whole enum is marked `ascii_case_insensitive`, you can specify `ascii_case_insensitive = false`
|
|
//! to disable case insensitivity on this variant.
|
|
//!
|
|
//! - `message=".."`: Adds a message to enum variant. This is used in conjunction with the `EnumMessage`
|
|
//! trait to associate a message with a variant. If `detailed_message` is not provided,
|
|
//! then `message` will also be returned when `get_detailed_message` is called.
|
|
//!
|
|
//! - `detailed_message=".."`: Adds a more detailed message to a variant. If this value is omitted, then
|
|
//! `message` will be used in it's place.
|
|
//!
|
|
//! - Structured documentation, as in `/// ...`: If using `EnumMessage`, is accessible via get_documentation().
|
|
//!
|
|
//! - `props(key="value")`: Enables associating additional information with a given variant.
