Enum InsertError 

pub enum InsertError<V> {
    Exists(V),
    CapacityExhausted,
}

Things that can go unhappily when trying to insert into a map

Variants

Exists(V)

The new value was inserted successfully but there was already a value in the map for that key.

CapacityExhausted

The map is at capacity and cannot fit any more pairs.

Trait Implementations

impl<V: Clone> Clone for InsertError<V>

fn clone(&self) -> InsertError<V>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<V: Debug> Debug for InsertError<V>

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

Formats the value using the given formatter.

impl<V: Ord> Ord for InsertError<V>

fn cmp(&self, other: &InsertError<V>) -> 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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<V: PartialEq> PartialEq for InsertError<V>

fn eq(&self, other: &InsertError<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.

impl<V: PartialOrd> PartialOrd for InsertError<V>

fn partial_cmp(&self, other: &InsertError<V>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
