Enum CanonicalizeError 

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

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)

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.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for CanonicalizeError

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

Formats the value using the given formatter.

impl Display for CanonicalizeError

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

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
