Enum BacktrackingRewrite 

pub enum BacktrackingRewrite {
    AtomicDecimalLoop,
    PossessiveDecimalDigits,
    AtomicDecimalTail,
    DeterministicDecimalTail,
    Refused(BacktrackingRewriteRefusal),
}

One recognized candidate, in AST traversal order. Unsupported shapes have no entry; absence of a report does not mean a pattern is safe.

Variants

AtomicDecimalLoop

Wrapped a decimal loop in an atomic group, retaining every capture.

PossessiveDecimalDigits

Made the primitive digit run possessive using choice-free bytecode.

AtomicDecimalTail

Made the complete decimal tail atomic, retaining its internal captures.

DeterministicDecimalTail

Evaluate the decimal prefix directly, preserving its last iteration’s captures.

Refused(BacktrackingRewriteRefusal)

Recognized the decimal loop but could not establish its safety.
