Trait ClonableFn 

pub trait ClonableFn: Category {
    type Output<'a, A: 'a, B: 'a>: Clone + Deref<Target = dyn Fn(A) -> B + 'a>;

    // Required method
    fn new<'a, A: 'a, B: 'a>(f: impl 'a + Fn(A) -> B) -> ApplyFn<'a, Self, A, B>;
}

Abstraction for clonable wrappers over closures.

This trait is implemented by “Brand” types (like ArcFnBrand and RcFnBrand) to provide a way to construct and type-check clonable wrappers over closures (Arc<dyn Fn...> or Rc<dyn Fn...>) in a generic context, allowing library users to choose between implementations at function call sites.

The lifetime 'a ensures the function doesn’t outlive referenced data, while generic types A and B represent the input and output types, respectively.

Required Associated Types

type Output<'a, A: 'a, B: 'a>: Clone + Deref<Target = dyn Fn(A) -> B + 'a>

Required Methods

fn new<'a, A: 'a, B: 'a>(f: impl 'a + Fn(A) -> B) -> ApplyFn<'a, Self, A, B>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl ClonableFn for ArcFnBrand

type Output<'a, A: 'a, B: 'a> = <ArcFnBrand as Kind1L2T>::Output<'a, A, B>

impl ClonableFn for RcFnBrand

type Output<'a, A: 'a, B: 'a> = <RcFnBrand as Kind1L2T>::Output<'a, A, B>
