CanonicalizeError

Enum CanonicalizeError 

Source
#[non_exhaustive]
pub enum CanonicalizeError { ReparseFailed { errors: Vec<String>, }, DirectiveCountMismatch { input: usize, reparsed: usize, }, }
Expand description

Error returned by canonicalize_directives.

Marked #[non_exhaustive] so that adding a future variant (e.g. a CanonicalizationTimeout for an async path, or a new guard for a future canonical-form rule) does not become a SemVer-breaking change. Consumers must use a _ => … arm.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

ReparseFailed

The synthesized intermediate failed to re-parse cleanly. Carries the rendered error messages so callers can surface a diagnostic; the source text itself is not retained because it’s an internal intermediate the caller has no control over.

Fields

§errors: Vec<String>

One rendered message per parse error from the intermediate text. Capped at the parser’s own error limit so this field is bounded.

§

DirectiveCountMismatch

The synthesized intermediate parsed cleanly but produced a different directive count than the input. This indicates the legacy emitter and the new parser disagree on what constitutes a directive — typically a future rustledger_core::Directive variant whose legacy text the CST parser silently swallows as comments / error-recovery trivia. Without this guard, the call would round-trip to truncated text with no error returned.

Fields

§input: usize

Number of directives the caller passed in.

§reparsed: usize

Number of directives the parser recovered from the synthesized text.
