Required Associated Types

The type of arguments tuple of this fn pointer. For example, the following types in each pair are equivalent.

    <fn() -> String as KnownFnPointer>::ArgsTuple
    ()

    <fn(i32) -> String as KnownFnPointer>::ArgsTuple
    (i32,)

    <fn(i32, bool) -> String as KnownFnPointer>::ArgsTuple
    (i32, bool)

The type of the fn pointer which accepts corresponding references of arguments. For example, the following types in each pair are equivalent.

    <fn() -> String as KnownFnPointer>::FnPointerWithRefArgs
    fn() -> String

    <fn(i32) -> String as KnownFnPointer>::FnPointerWithRefArgs
    fn(&i32) -> String

    <fn(i32, bool) -> String as KnownFnPointer>::FnPointerWithRefArgs
    fn(&i32, &bool) -> String

The corresponding dyn FnOnce type. For example, the following types in each pair are equivalent.

    <fn() -> String as KnownFnPointer>::DynFnOnce
    dyn FnOnce() -> String

    <fn(i32) -> String as KnownFnPointer>::DynFnOnce
    dyn FnOnce(i32) -> String

    <fn(i32, bool) -> String as KnownFnPointer>::DynFnOnce
    dyn FnOnce(i32, bool) -> String

The corresponding dyn DynFnMut type. For example, the following types in each pair are equivalent.

    <fn() -> String as KnownFnPointer>::DynFnMut
    dyn FnMut() -> String

    <fn(i32) -> String as KnownFnPointer>::DynFnMut
    dyn FnMut(i32) -> String

    <fn(i32, bool) -> String as KnownFnPointer>::DynFnMut
    dyn FnMut(i32, bool) -> String

The corresponding dyn DynFn type. For example, the following types in each pair are equivalent.

    <fn() -> String as KnownFnPointer>::DynFn
    dyn Fn() -> String

    <fn(i32) -> String as KnownFnPointer>::DynFn
    dyn Fn(i32) -> String

    <fn(i32, bool) -> String as KnownFnPointer>::DynFn
    dyn Fn(i32, bool) -> String
