valued-enums
Macros collection and specify trait for creating valued or python-like enums.
Installation
[dependencies.valued-enums]
version = "1.1.9"
Example
When you writing your enums collection, i recommend using pub
to expand the trait in the rest of your project.
use valued_enums::*;
py_enum! {
PyLikeEnum(u8):
ONE = 1
TWO = 2
THREE = 3
DUPLICATE = 3
}
rust_enum! {
enum RustLikeEnum((u8, u8)) {
ONE = (1, 1),
TWO = (2, 2),
THREE = (3, 3),
DUPLICATE = (3, 3),
}
}
mod some_inner_module {
use crate::valued_enum;
valued_enum! {
#[derive(Debug)]
pub enum VisibleCustomizeEnum(&'static str) {
pub(crate) CRATE_VISIBLE = "crate",
pub PUBLIC_VISIBLE = "public",
PRIVATE = "private",
}
}
}
#[derive(PartialEq, Eq)]
struct Point(i32, i32);
py_enum! {
PointEnum(Point):
A = Point(1, 2)
B = Point(3, 4)
}
fn main() {
println!("Equal enum with their value type: {}", PyLikeEnum::ONE.equal(&1));
println!("Get key: {}", RustLikeEnum::ONE.key());
println!("Get value: {}", PyLikeEnum::TWO.value());
println!("Get ref value: &{}", PyLikeEnum::THREE.ref_value());
println!("Get all keys: {:?}", RustLikeEnum::keys());
println!("Get all values: {:?}", PyLikeEnum::values());
println!("Get all variants: {:?}", some_inner_module::VisibleCustomizeEnum::variants());
println!("Convert from title to enum: {}", some_inner_module::VisibleCustomizeEnum::from_key("PRIVATE").unwrap().value());
println!("Convert from value to enum: {}", PyLikeEnum::from_value(&3).unwrap().key());
}
