I got tired of writing boilerplate to wire up functions to traits, so I made a helper
Decorate an impl block with #[dizpacho]
and you can then use dizpacho
attributes
on methods and associated functions to wire them up to whatever trait you like!
struct TooLazyToType(String);
struct OtherThing;
#[dizpacho::dizpacho]
impl TooLazyToType {
/// Just call my new() function for default!
#[dizpacho(Default::default)]
fn new() -> Self {
Self("howdy!".to_string())
}
}
assert_eq!(&TooLazyToType::default().0, "howdy!");
struct TooLazyToType(String);
struct OtherThing;
#[dizpacho::dizpacho]
impl TooLazyToType {
#[dizpacho(std::ops::Deref<Target = str>::deref)]
fn as_str(&self) -> &str {
&self.0
}
}
#[dizpacho::dizpacho]
impl OtherThing {
/// You can even do generics!
#[dizpacho(From<Self>::from for TooLazyToType)]
fn from_other(thing: OtherThing) -> TooLazyToType {
TooLazyToType("I came from the other thing!".to_string())
}
}
assert!(TooLazyToType::from(OtherThing).0.ends_with("thing!"))
