Struct FutureChain 

pub struct FutureChain<T> { /* private fields */ }

A chain of lazy computations that can be built up and then forced.

Each step maps the previous value to the next. This is a simplified synchronous “future” / continuation chain.

Implementations

impl<T: 'static> FutureChain<T>

pub fn new<F: FnOnce() -> T + 'static>(init: F) -> Self

Create a chain starting from init.

pub fn then<F: FnOnce(T) -> T + 'static>(self, f: F) -> Self

Add a transformation step.

pub fn force(self) -> T

Force the chain, running all computations in order.

pub fn step_count(&self) -> usize

Number of steps in the chain.
