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.

TooShort

Input was shorter than the required prefix.

Fields

need: usize

Required byte count.

have: usize

Available byte count.

TruncatedAt

Input ended while reading a marker or marker segment.

Fields

offset: usize

Byte offset where the truncated segment begins.

segment: &'static str

Segment being read.

InvalidMarker

A codestream marker did not start with 0xFF.

Fields

offset: usize

Byte offset of the invalid marker.

marker: u8

Byte found where the marker code was expected.

MissingRequiredMarker

A required codestream marker was absent.

Fields

marker: &'static str

Missing marker name.

InvalidSegment

A generic marker segment was malformed.

Fields

offset: usize

Byte offset of the segment length.

what: &'static str

Description of the invalid segment.

InvalidSiz

The SIZ marker segment was malformed or unsupported.

Fields

what: &'static str

Description of the invalid SIZ segment.

InvalidCod

The COD marker segment was malformed or unsupported.

Fields

what: &'static str

Description of the invalid COD segment.

Unsupported

The header is valid, but outside the public inspection contract.

Fields

what: &'static str

Description of the unsupported feature.
