Stable error classes. These distinguish failure kinds rather than prose.

Variants

Io

Host I/O failure (read/write/rename/fsync).

Usage

Command-line or API misuse.

InvalidContainer

The container framing/header is malformed.

UnsupportedVersion

The container declares a version this build does not implement.

UnsupportedFeature

The container declares a mandatory feature this build does not support.

IntegrityMismatch

A digest, length, or checksum disagreed with the declared value.

ResourceLimit

A declared or configured resource bound was exceeded.

InvalidGraph

The reconstruction graph is malformed (cycles, bad references, gaps).

InvalidModel

An entropy model descriptor is malformed.

EntropyDecode

An entropy channel failed to decode.

InvalidPdfStructure

A PDF physical/lexical structure error (Phase 3+).

CodecReplay

An exact codec-replay candidate failed (Phase 6+).

MissingExternalObject

A referenced external store object is missing (Phase 9+).

CoverageViolation

The coverage certificate is invalid (gaps or overlapping authorities).

ReconstructionMismatch

Materialization completed but did not equal the source.

Cancelled

The operation was cooperatively cancelled.

InvalidZipStructure

A ZIP container structure error (Phase 12+): malformed or contradictory local/central/ZIP64 records, an ambiguous byte cover, a broken descriptor, multi-disk layout, or a hostile member name.

InvalidXmlStructure

An XML part structure error (Phase 12+, reserved): malformed or forbidden constructs (DOCTYPE/XXE, encoding tricks) in a package part.

InvalidPackageStructure

An OPC/OCF package structure error (Phase 12+, reserved): a missing or ambiguous main part, content-type abuse, mimetype trick, or an ambiguous part-name identity.

InternalInvariant

A bug in this implementation; never a description of malformed input.

Implementations

impl ErrorClass

pub const fn exit_code(self) -> i32

Stable, documented CLI exit code for this class.

pub const fn as_str(self) -> &'static str

Short stable identifier used in receipts and machine-readable output.
