Enum EntryChange

pub enum EntryChange {
    Inserted(Out),
    Updated(Out, Out),
    Removed(Out),
}

Expand description

A single change done over a map-component of shared data type.

Variants§

§

Inserted(Out)

Informs about a new value inserted under specified entry.

§

Updated(Out, Out)

Informs about a change of old value (1st field) to a new one (2nd field) under a corresponding entry.

§

Removed(Out)

Informs about a removal of a corresponding entry - contains a removed value.
