Struct regex_automata::meta::error::RetryQuadraticError

pub(crate) struct RetryQuadraticError(());

An error that occurs when potential quadratic behavior has been detected when applying either the “reverse suffix” or “reverse inner” optimizations.

When this error occurs, callers should abandon the “reverse” optimization and use a normal forward search.
