pub enum TailCall<T> {
    Continue(Box<dyn Fn() -> TailCall<T>>),
    Done(T),
}

Represents a tail call that can be either a continuation or a completed result.

Variants

Continue(Box<dyn Fn() -> TailCall<T>>)

A continuation that holds a deferred computation.

Done(T)

A completed computation with a result.

Implementations

impl<T> TailCall<T>

pub fn apply(&self) -> TailCall<T>

Applies the current step and returns the next TailCall.

Panics

Panics if called on a completed computation.

pub fn is_completed(&self) -> bool

Checks whether the computation is completed.

pub fn result(&self) -> Option<&T>

Returns the result if the computation is completed.

pub fn invoke(self) -> T

Executes the computation by iterating until a completed result is found.
