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

impl ExtractKind

pub fn is_prefix(&self) -> bool

Returns true if this kind is the Prefix variant.

pub fn is_suffix(&self) -> bool

Returns true if this kind is the Suffix variant.

Trait Implementations

impl Clone for ExtractKind

fn clone(&self) -> ExtractKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExtractKind

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

Formats the value using the given formatter.

impl Default for ExtractKind

fn default() -> ExtractKind

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
