Struct RegExpObj 

pub struct RegExpObj {
    pub re: Rc<Regex>,
    pub source: String,
    pub flags: String,
    pub global: bool,
    pub ignore_case: bool,
    pub multiline: bool,
    pub dot_all: bool,
    pub sticky: bool,
    pub unicode: bool,
    pub last_index: U16Index,
}

A RegExp object: the compiled fancy_regex::Regex plus the JS-visible source, flag booleans, and the mutable lastIndex cursor (used by g/y matching). fancy-regex adds lookaround + backreferences on top of the Rust regex fast path, so the JS grammar node-js can accept is a near-superset.

Fields

re: Rc<Regex>

The translated regex. Construction of a pattern fancy-regex still cannot express (documented in BUGS.md) throws at RegExp build time, so a live RegExpObj always holds a compiled engine.

Shared (Rc) rather than owned, because a regex LITERAL builds a fresh RegExpObj on every evaluation — it has to, since lastIndex is per-object mutable state — while the compiled engine behind it is immutable and identical every time. See regexp::compiled.

source: String

flags: String

global: bool

ignore_case: bool

multiline: bool

dot_all: bool

sticky: bool

unicode: bool

last_index: U16Index

lastIndex, in UTF-16 code units; advanced by exec/test under the g/y flags. The newtype keeps it from being confused with the regex engine’s byte offsets, which are the same shape and differ off the BMP.

Trait Implementations

impl Clone for RegExpObj

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
