Struct ItemChange 

pub struct ItemChange<T> { /* private fields */ }

The change of one item of a list (ItemChange<T>).

Implementations

impl<T> ItemChange<T>

pub fn new( reason: ListChangeReason, current: T, previous: Option<T>, current_index: Option<usize>, previous_index: Option<usize>, ) -> Self

ItemChange(ListChangeReason, T, in Optional<T>, int, int).

pub fn reason(&self) -> ListChangeReason

The reason (Reason).

pub fn current(&self) -> &T

The item (Current).

pub fn previous(&self) -> Option<&T>

The item that was replaced (Previous).

pub fn current_index(&self) -> Option<usize>

The index of the item (CurrentIndex; -1 upstream when none).

pub fn previous_index(&self) -> Option<usize>

The previous index of a moved item (PreviousIndex).
