Expand description
Clone should be cheap if you are parsing typescript because typescript syntax requires backtracking.
Required methods
fn set_expr_allowed(&mut self, allow: bool)
fn token_context(&self) -> &TokenContexts
fn token_context_mut(&mut self) -> &mut TokenContexts
fn set_token_context(&mut self, _c: TokenContexts)
Implementors should use Rc<RefCell<Vec
It is required because parser should backtrack while parsing typescript code.
fn add_module_mode_error(&self, error: Error)
fn add_module_mode_error(&self, error: Error)
Add an error which is valid syntax in script mode.
This errors should be dropped if it’s not a module.
Implementor should check for if Context.module, and buffer errors if module is false. Also, implementors should move errors to the error buffer on set_ctx if the parser mode become module mode.
