Enum regex_syntax::hir::literal::ExtractKind

#[non_exhaustive]
pub enum ExtractKind {
    Prefix,
    Suffix,
}

The kind of literals to extract from an Hir expression.

The default extraction kind is Prefix.

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.

Prefix

Extracts only prefix literals from a regex.

Suffix

Extracts only suffix literals from a regex.

Note that the sequence returned by suffix literals currently may not correctly represent leftmost-first or “preference” order match semantics.

Implementations
