Implementations

pub fn get_state(&self) -> &Variant

pub fn has_value(&self) -> ExecResult<bool>

pub fn get_value(&self) -> ExecResult<Variant>

pub fn advance(&mut self) -> ExecResult<()>

Trait Implementations

impl GcTrace for IterState

fn trace(&self)

SAFETY: Must call Gc::mark_trace() on every reachable Gc handle

fn size_hint(&self) -> usize

If the GcTrace owns any allocations, this should return the extra allocated size. If the allocation can change size, like a Vec, then don’t include it in the size hint, or return a const estimate of the average size.

fn cleanup(&self)

impl IntoIterator for IterState

type Item = Result<Variant, Box<RuntimeError>>

The type of the elements being iterated over.

type IntoIter = Iter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
