Struct tramp::Thunk

pub struct Thunk<'a, T> { /* fields omitted */ }

A delayed computation. This can be used in lazy evaluation environments. Also, it is used to delay a tail call and emulate TCO (tail call optimization).

Methods

impl<'a, T> Thunk<'a, T>

pub fn new(     fun: impl FnOnce() -> T + 'a ) -> Self

Creates a new thunk from the given function. Probably you will end up passing closures to this function.

pub fn compute(self) -> T

Computes the result of this thunk, i.e. forces evaluation to happen.

Trait Implementations

impl<'a, T> Debug for Thunk<'a, T>

fn fmt(&self, fmtr: &mut Formatter) -> Result

Formats the value using the given formatter.
