Struct SavePoint 

pub struct SavePoint { /* private fields */ }

Store state of the lexer and allow rescanning from that point. Port of the C++ JSLexer::SavePoint (JSLexer.h:751-821).

DEVIATION: the C++ SavePoint holds a JSLexer * and exposes restore(). In Rust a save point cannot hold a &mut JSLexer across an intervening advance (which also borrows the lexer mutably), so it is a plain value snapshot and restore takes &mut JSLexer.

Implementations

impl SavePoint

pub fn restore(self, lexer: &mut JSLexer<'_>)

Restore the state of lexer to the originally saved state. Port of JSLexer::SavePoint::restore (JSLexer.h:797-820).
