Trait Implementations§

Source§

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.

Source§

fn drop(&mut self)

Executes the destructor for this type. Read more
Source§

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

Source§

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

Converts to this type from the input type.
