Struct OccupiedError

pub struct OccupiedError<'a, V: 'a> {
    pub current: &'a V,
    pub not_inserted: V,
}

An error returned by try_insert when the key already exists.

Contains the existing value, and the value that was not inserted.

Fields

current: &'a V

The value in the map that was already present.

not_inserted: V

The value which was not inserted, because the entry was already occupied.

Trait Implementations

impl<'a, V: Debug + 'a> Debug for OccupiedError<'a, V>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, V: PartialEq + 'a> PartialEq for OccupiedError<'a, V>

fn eq(&self, other: &OccupiedError<'a, V>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
