Struct regex::exec::Exec

pub struct Exec {
    ro: Arc<ExecReadOnly>,
    cache: CachedThreadLocal<RefCell<ProgramCacheInner>>,
}

Exec manages the execution of a regular expression.

In particular, this manages the various compiled forms of a single regular expression and the choice of which matching engine to use to execute a regular expression.

Fields

ro: Arc<ExecReadOnly>

All read only state.

cache: CachedThreadLocal<RefCell<ProgramCacheInner>>

Caches for the various matching engines.

Methods

impl Exec

pub fn searcher(&self) -> ExecNoSync

Get a searcher that isn't Sync.

pub fn searcher_str(&self) -> ExecNoSyncStr

Get a searcher that isn't Sync and can match on &str.

pub fn into_regex(self) -> Regex

Build a Regex from this executor.

pub fn into_regex_set(self) -> RegexSet

Build a RegexSet from this executor.

pub fn into_byte_regex(self) -> Regex

Build a Regex from this executor that can match arbitrary bytes.

pub fn into_byte_regex_set(self) -> RegexSet

Build a RegexSet from this executor that can match arbitrary bytes.

pub fn regex_strings(&self) -> &[String]

The original regular expressions given by the caller that were compiled.

pub fn capture_names(&self) -> &[Option<String>]

Return a slice of capture names.

Any capture that isn't named is None.

pub fn capture_name_idx(&self) -> &Arc<HashMap<String, usize>>

Return a reference to named groups mapping (from group name to group position).

Trait Implementations

impl Clone for Exec

fn clone(&self) -> Exec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<Exec> for Regex

A constructor for Regex from an Exec.

This is hidden because Exec isn't actually part of the public API.

fn from(exec: Exec) -> Regex

Performs the conversion.

impl From<Exec> for RegexSet

fn from(exec: Exec) -> Self

Performs the conversion.

impl From<Exec> for RegexSet

fn from(exec: Exec) -> Self

Performs the conversion.

impl From<Exec> for Regex

fn from(exec: Exec) -> Regex

Performs the conversion.
