Enum DecodeErrorClass 

#[non_exhaustive]
pub enum DecodeErrorClass {
    InputTooShort {
        need: usize,
        have: usize,
    },
    InputTruncatedAt {
        offset: usize,
        segment: &'static str,
    },
    Unsupported {
        what: &'static str,
    },
    Backend,
}

Backend-neutral classification used by codec adapters.

This preserves the small amount of structured information that adapters need without requiring each adapter to match the complete native error hierarchy independently.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InputTooShort

Input ended before a required fixed-size read.

Fields

need: usize

Required byte count.

have: usize

Available byte count.

InputTruncatedAt

Input ended while reading a named segment.

Fields

offset: usize

Byte offset where truncation was detected.

segment: &'static str

Stable segment label.

Unsupported

The codestream or container uses an unsupported feature.

Fields

what: &'static str

Stable user-facing feature label.

Backend

All other native decoder failures.
