Enum OnceError 

pub enum OnceError<E> {
    Provider(E),
    OutputWidth {
        expected: usize,
        actual: usize,
    },
}

Failure of a one-shot check, apart from every completed comparison.

Variants

Provider(E)

Original provider failure, including its resource refusal.

OutputWidth

The provider’s output contradicts the fixed width of its own identity. This is a provider contract failure, not malformed document data.

Fields

expected: usize

Width promised by the resolved identity.

actual: usize

Width actually returned.
