Struct regex_automata::meta::error::RetryFailError

source ·
pub(crate) struct RetryFailError {
    offset: usize,
}
Expand description

An error that occurs when a regex engine “gives up” for some reason before finishing a search. Usually this occurs because of heuristic Unicode word boundary support or because of ineffective cache usage in the lazy DFA.

When this error occurs, callers should retry the regex search with a different regex engine.

Note that this has convenient From impls that will automatically convert a MatchError into this error. This works because the meta regex engine internals guarantee that errors like HaystackTooLong and UnsupportedAnchored will never occur. The only errors left are Quit and GaveUp, which both correspond to this “failure” error.
