Enum ChangeReason 

pub enum ChangeReason {
    Add = 0,
    Update = 1,
    Remove = 2,
    Refresh = 3,
    Moved = 4,
}

The reason of a change of a cache (ChangeReason).

Variants

Add = 0

An item was added (Add).

Update = 1

An item replaced the item of its key (Update).

Remove = 2

An item was removed (Remove).

Refresh = 3

An item asks to be evaluated again by the operators downstream: filters, sorts, groups (Refresh).

Moved = 4

An item moved within a sorted collection (Moved).

impl Ord for ChangeReason

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self
