Struct ParserState

pub struct ParserState {
    pub allow_loop_control: bool,
}

State that can be used to determine if certain parse trees are valid (e.g. if a checking if a break expression is inside a loop).

The state cannot be mutated directly; it can only be changed when parsing using the Parser::try_parse_with_state method.

Fields

allow_loop_control: bool

Whether loop control expressions are allowed in the current context. This is used to determine if a break or continue expression is valid.
