Parse error categories — one per acceptance-gate rejection.

Variants

TooShort

Input shorter than HEADER_BYTE_SIZE.

Fields

got: usize

BadMagic

Magic bytes do not match MAGIC_10D.

Fields

got: [u8; 4]

UnknownVersion

Version is not HEADER_VERSION.

Fields

got: u16

NonZeroPadding

A padding/reserved field is non-zero (the “zero padding” gate).

Fields

field: &'static str

UndefinedAxisRole

An axis role byte is not a defined AxisRole variant.

Fields

axis_index: usize

got: u8

MetricDivergence(String)

The metric-completeness descriptor diverges from full_distance’s actual v-branch behaviour. Carries the divergence detail.

BadSectionTablePointer

The section-table pointer in the header is inconsistent: offset is not 0 (no table) and not >= HEADER_BYTE_SIZE and within the file, or section_count exceeds MAX_SECTION_COUNT, or exactly one of (offset, count) is zero.

Fields

offset: u32

count: u32

Trait Implementations

impl Clone for HeaderParseError

fn clone(&self) -> HeaderParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderParseError

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

Formats the value using the given formatter.

impl Display for HeaderParseError

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

Formats the value using the given formatter.

impl Error for HeaderParseError

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 HeaderParseError

fn eq(&self, other: &HeaderParseError) -> 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.
