Cross-scan progressive coefficient-state violation.

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.

DuplicateInitial

An initial scan selected a coefficient that was already initialized.

Fields

previous_al: u8

Approximation-low value retained from the earlier scan.

al: u8

Approximation-low value declared by the duplicate scan.

RefinementBeforeInitial

A refinement scan selected a coefficient with no initial scan.

Fields

ah: u8

Approximation-high value declared by the refinement scan.

al: u8

Approximation-low value declared by the refinement scan.

RefinementMismatch

A refinement scan skipped or repeated an approximation level.

Fields

previous_al: u8

Approximation-low value retained from the previous scan.

ah: u8

Approximation-high value declared by the refinement scan.

al: u8

Approximation-low value declared by the refinement scan.

MissingInitialDc

EOI or physical EOF arrived before an initial DC scan for the component.
