Struct ApplyFn 

pub struct ApplyFn<'a, A, B> { /* private fields */ }

An ApplyFn is a function from A to B wrapped in something Rust’s type system can more easily digest. Arguments for Apply::apply() are required to be of this type rather than an arbitrary type matching Fn(A) -> B.

Implementations

impl<'a, A, B> ApplyFn<'a, A, B>

pub fn apply(&self, a: A) -> B

Apply the wrapped function to a value of type A.

Trait Implementations

impl<'a, A, B> Debug for ApplyFn<'a, A, B>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, A, B, F> From<F> for ApplyFn<'a, A, B>

where F: 'a + Fn(A) -> B,

fn from(f: F) -> Self

Converts to this type from the input type.
