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.

E0001

Malformed timestamp.

E0002

Unknown profile tag.

E0003

Mixed text forms in one string (Rule D).

E0004

Group value out of range (> 3124).

E0005

Invalid base-5 digit.

E0006

Non-contiguous tier sequence.

E0007

Calendar rendering without a kind/id qualifier (§6.6).

E0010

Locale table load failure.

E0011

Duplicate name in the active locale table (Rule N).

E0012

Unknown key in an HJSON data file.

E0013

Profile lacks a datum_provenance record (Rule Q.4).

E0020

Result precedes the datum (Rule Z).

E0021

Result exceeds DOMAIN (Rules O, W).

E0022

Window inversion, lo > hi (Rule U).

E0023

Comparison indeterminate at the stated precision (Rule T).

E0024

Lossy rendering requested without a rounding mode (Rule R).

E0025

BIG_BANG_CLAIM or its half-width used as a computational operand (Rule Q.3). Reaching this at runtime is an internal invariant violation; the type system is supposed to make it unreachable, and §21.3-3 requires a compile-fail test proving so.

E0030

Binary form is not 64 bytes (Rule B).

E0031

Instant outside UCID range (Rule I).

E0032

Invalid Crockford base-32.

E0040

Civil date outside the renderable range (§14.3). Never a panic.

E0041

Invalid civil date for the stated calendar.

E0042

second = 60 outside a leap-second instant.

E0043

Foreign-unit input finer than the bridge constant permits (Rules A, R, Y).

E0050

Profile mismatch (Rule P).

E0060

Body parameter missing required provenance or as-measured value (Rules C, Y).

E0061

Leap-rule derivation cannot meet the requested drift bound.

E0062

Calendar has no anchor; local fields cannot be produced (Rule J.3).

E0063

Anchor phase definition not evaluable for this body’s parameters (Rule J.4).

E0064

Grouping cycle requested but none derivable from any satellite (§9.6).

E0065

Legacy calendar supplied where a derived calendar is required (Rule K.6).

E0070

Division by zero, or by an interval containing zero (Appendix H.3); also a cosmology inversion that failed to bracket.

E0071

Requested enclosure width unreachable at the permitted depth (Rule X).

E0080

Tier index outside the profile’s grid.

Implementations

impl Code

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