Enum KeyedRosterAssignmentError 

pub enum KeyedRosterAssignmentError<K, S, const N: usize> {
    Empty(Empty),
    Overflow(Overflow),
    ForeignReferences(NonEmpty<ForeignRosterReference<K>, N>),
    DuplicateReferences(NonEmpty<DuplicateKey<K, N>, N>),
    ReusedPayloadSeats(NonEmpty<DuplicateKey<S, N>, N>),
    MissingMembers(NonEmpty<UnassignedRosterMember<K>, N>),
}

How an offered payload roster refuses exact assignment to a keyed denominator.

Variants

Empty(Empty)

Nothing was offered.

Overflow(Overflow)

Too much was offered.

ForeignReferences(NonEmpty<ForeignRosterReference<K>, N>)

One or more offered payloads name a key outside the denominator.

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

One or more denominator keys were referenced more than once.

ReusedPayloadSeats(NonEmpty<DuplicateKey<S, N>, N>)

One or more caller-declared payload-seat keys were reused.

MissingMembers(NonEmpty<UnassignedRosterMember<K>, N>)

One or more denominator members received no payload.

Trait Implementations

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
