bitwise_boolean

A Rust macro to generate bitwise boolean getters and setters for a struct.

Usage

To use the bitwise_boolean macro, add the following to your Cargo.toml file:

[dependencies]
bitwise_boolean = "0.1.0"

Then, use the macro in your code:

use bitwise_boolean::BitwiseBoolean;#[derive(Default,BitwiseBoolean)]structExampleSettingsData{// up to 8 flags total#[bitwise_bool( admin, agreed_to_terms, banned, random_other_flag)]pubbooleans:u8,}structExampleSettings{data:ExampleSettingsData,}implExampleSettings{fnnew() -> Self{Self{data:ExampleSettingsData::default(),}}}

Now, you can use the bitwise boolean getters and setters in your code:

letmut settings = ExampleSettings::new();
settings.data.set_admin(true);assert!(settings.data.admin());assert!(!settings.data.agreed_to_terms());assert!(!settings.data.banned());assert!(!settings.data.random_other_flag());
settings.data.set_agreed_to_terms(true);assert!(settings.data.admin());assert!(settings.data.agreed_to_terms());assert!(!settings.data.banned());assert!(!settings.data.random_other_flag());
settings.data.set_banned(true);assert!(settings.data.admin());assert!(settings.data.agreed_to_terms());assert!(settings.data.banned());assert!(!settings.data.random_other_flag());
settings.data.set_random_other_flag(true);assert!(settings.data.admin());assert!(settings.data.agreed_to_terms());assert!(settings.data.banned());assert!(settings.data.random_other_flag());

Limitations

The bitwise_boolean macro currently supports up to 8 flags per struct.
