Struct Generator

pub struct Generator<'a, Input: 'a, Output: 'a, Stack: Stack> { /* private fields */ }

Generator wraps a closure and allows suspending its execution more than once, returning a value each time.

If the closure finishes each other call to resume will yield None. If the closure panics the unwind will happen correctly across contexts.

Implementations

impl<'a, Input, Output, Stack> Generator<'a, Input, Output, Stack>

where Input: 'a, Output: 'a, Stack: Stack,

pub fn new<F>(stack: Stack, f: F) -> Generator<'a, Input, Output, Stack>

where F: FnOnce(&Yielder<Input, Output>, Input) + 'a,

Create a new generator from a stack and closure.

pub fn resume(&mut self, input: Input) -> Option<Output>

Resume the generator yielding the next value.

pub fn started(&self) -> bool

Returns true if the execution of the passed in closure started

pub fn finished(&self) -> bool

Returns true if the generator finished running.

pub fn stack(self) -> Stack

Consume the generator and extract the stack.
