Enum TranscodeEncodeError 

pub enum TranscodeEncodeError<E, V> {
    Failure(TranscodeFailure),
    Unencodable {
        input_index: usize,
        value: Option<V>,
    },
    Domain(TranscodeDomainError<E>),
}

Error reported by an encode-oriented transcode operation.

Variants

Failure(TranscodeFailure)

Framework-level transcode failure.

Unencodable

The input value cannot be encoded by the target codec and policy.

Fields

input_index: usize

Absolute input index of the value being encoded.

value: Option<V>

Value being encoded, when the transcoder can expose it.

Domain(TranscodeDomainError<E>)

Domain-specific codec, charset, or policy error.

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
