Enum BackendBatchProjectionError 

pub enum BackendBatchProjectionError {
    Cardinality {
        expected: usize,
        actual: usize,
    },
    IllegalSource,
    IllegalReplacement,
    DifferentSpan,
}

Validation failure for an ordered one-to-one backend replacement span.

Variants

Cardinality

Replacement cardinality differed from the held span.

Fields

expected: usize

Number of authoritative held inputs.

actual: usize

Number of proposed replacements.

IllegalSource

A held source was not attributable at this pipeline position.

IllegalReplacement

A proposed replacement was illegal or not reconstructable.

DifferentSpan

Replacements would consume a different protocol span than the sources.
