Provenance-section read/write/validate error.

Variants

PayloadTooShort

The payload is too short for the mini-header.

Fields

got: usize

need: usize

BadMagic

The payload magic is not PROVENANCE_MAGIC.

Fields

got: u32

UnsupportedVersion

The payload version is not PROVENANCE_SECTION_VERSION.

Fields

got: u16

NonZeroReserved

The mini-header reserved_u32 is non-zero.

UnknownFlags

Unknown flags bit set (only bit 0 is defined in v1).

Fields

got: u16

FieldTooLarge

A variable-length field exceeds MAX_PROVENANCE_FIELD.

Fields

field: &'static str

got: usize

max: usize

PayloadTruncated

The payload is too short for the declared field lengths.

Fields

expected: usize

got: usize

OutputBufferTooSmall

The output buffer is too small.

Fields

needed: usize

have: usize

VcFlagInconsistent

The FLAG_HAS_VC bit and vc_len disagree.

Fields

has_vc: bool

vc_len: u32

NonUtf8

A field declared as utf8 (media type / licence) is not valid utf8.

Fields

field: &'static str

SourceDigestMismatch

Validate gate: the carried source bytes do not hash to the declared source_digest — the sidecar’s source is not authentic to its claim.

Fields

expected: u32

got: u32

MissingLicence

Validate gate: no licence is present (context was stripped).

Trait Implementations

impl Clone for ProvenanceSectionError

fn clone(&self) -> ProvenanceSectionError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProvenanceSectionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ProvenanceSectionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ProvenanceSectionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ProvenanceSectionError

fn eq(&self, other: &ProvenanceSectionError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
