Funkjon - a bad macro
With funkjon, you too can create your very own function.
Usage:
funkjon!(greet :: name {
println!("Hello, {name}.");
} as (String) -> Unit);
greet("David".to_string());
By the way, Unit
is the return type. It is equivalent to ()
.
You can change it by just putting something other than Unit
next to the right arrow (->
).
Usage with generics:
funkjon!(greet ::<T: std::fmt::Display>:: name {
println!("Hello, {name}.");
} as (T) -> Unit);
greet("David");
Or with a where clause
funkjon!(greet ::<T>:: name {
println!("Hello, {name}.");
} as (T) -> Unit
where T: std::fmt::Display,
);
greet("David");
