Struct PersistantElementIter

pub struct PersistantElementIter { /* private fields */ }

Focus systems need a iterator that can persist through changes in the crate::prelude::RealDom This iterator traverses the tree depth first. You can iterate through it with PersistantElementIter::next and PersistantElementIter::prev. The iterator loops around when it reaches the end or the beginning.

Implementations

impl PersistantElementIter

pub fn create<V: FromAnyValue + Send + Sync>(rdom: &mut RealDom<V>) -> Self

Create a new iterator in the RealDom

pub fn next<V: FromAnyValue + Send + Sync>( &mut self, rdom: &RealDom<V>, ) -> ElementProduced

get the next element

pub fn prev<V: FromAnyValue + Send + Sync>( &mut self, rdom: &RealDom<V>, ) -> ElementProduced

get the previous element
