Entropy condition that made a progressive scan terminator invalid.

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.

ResidualEobRun

An EOB run extends beyond the final coded block in the scan.

Fields

remaining: u32

Number of blocks still covered after the scan’s final block.

ExcessEntropy

Complete entropy bytes or too many buffered bits remain after decoding.

Fields

unread_bytes: usize

Complete bytes between the decoder cursor and the parsed boundary.

unread_bits: u8

Real (non-synthetic) bits still buffered by the entropy reader.

InvalidPadding

The final partial entropy byte is not padded exclusively with one bits.

Fields

unread_bits: u8

Number of real padding bits that remained buffered.

TerminalMismatch

The entropy reader observed a different boundary than the parser.

Fields

expected_offset: usize

Parser-recorded absolute terminal offset.

expected_marker: Option<u8>

Parser-recorded marker, or None for physical EOF.

found_offset: Option<usize>

Entropy-reader absolute marker offset, or None at physical EOF.

found_marker: Option<u8>

Entropy-reader marker, or None at physical EOF.
