Enum KeyedRosterError 

pub enum KeyedRosterError<K, const N: usize> {
    Empty(Empty),
    Overflow(Overflow),
    DuplicateKeys(NonEmpty<DuplicateKey<K, N>, N>),
}

How construction of a caller-keyed roster refuses.

Variants

Empty(Empty)

Nothing was offered.

Overflow(Overflow)

Too much was offered.

DuplicateKeys(NonEmpty<DuplicateKey<K, N>, N>)

One or more caller-declared keys occurred more than once.

Trait Implementations

impl<K: Clone, const N: usize> Clone for KeyedRosterError<K, N>

fn clone(&self) -> KeyedRosterError<K, N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug, const N: usize> Debug for KeyedRosterError<K, N>

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
