Macro of_method 

macro_rules! of_method {
    ($ty:ident :: $method:ident) => { ... };
    ($ty:ident :: $method:ident ::<$($arg:ty),*>) => { ... };
    (<$ty:ty> :: $method:ident) => { ... };
    (<$ty:ty> :: $method:ident ::<$($arg:ty),*>) => { ... };
}

Get the name of the given method as a String.

This macro resolves Self to the appropriate type when used inside an impl block.

By default, this macro expects a simple type identifier like Type::field. To use types with qualified path or generic parameters, wrap the type in angle brackets like <Type<T>>::field or <module::Type>::field.

This macro checks that the method exists on the given type. If either the type or method is renamed via refactoring tools, the macro call will be updated accordingly.

Due to implementation limitations, you cannot use ::<..> syntax to exclude generic parameters. Use explicit type arguments instead.

Examples

struct MyStruct;
impl MyStruct {
    fn my_method(&self) {}
    fn my_generic_method<T>(&self) {}
}
struct MyGenericStruct<T>(std::marker::PhantomData<T>);
impl<T> MyGenericStruct<T> {
    fn my_method(&self) {}
    fn my_generic_method<U>(&self) {}
}
assert_eq!(pretty_name::of_method!(MyStruct::my_method), "MyStruct::my_method");
assert_eq!(pretty_name::of_method!(MyStruct::my_generic_method::<u32>), "MyStruct::my_generic_method::<u32>");
assert_eq!(pretty_name::of_method!(<MyGenericStruct<u32>>::my_method), "<MyGenericStruct<u32>>::my_method");
assert_eq!(pretty_name::of_method!(<MyGenericStruct<u32>>::my_generic_method::<String>), "<MyGenericStruct<u32>>::my_generic_method::<String>");
