Trait Implementations

impl Drop for RuleIter<'_>

Make sure that the iterator was completely consumed when the iterator is dropped - that we didn’t leave any partially-parsed tokens.

This is not strictly necessary, but it’s a good way to catch bugs.

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> From<Pairs<'a, Rule>> for RuleIter<'a>

fn from(iter: Pairs<'a, Rule>) -> Self

Converts to this type from the input type.
