Trait druid::widget::ListIter

pub trait ListIter<T>: Data {
    fn for_each(&self, cb: impl FnMut(&T, usize));
    fn for_each_mut(&mut self, cb: impl FnMut(&mut T, usize));
    fn data_len(&self) -> usize;
}

This iterator enables writing List widget for any Data.

Required methods

fn for_each(&self, cb: impl FnMut(&T, usize))

Iterate over each data child.

fn for_each_mut(&mut self, cb: impl FnMut(&mut T, usize))

Iterate over each data child. Keep track of changed data and update self.

fn data_len(&self) -> usize

Return data length.
