Struct ExprParser 

pub(crate) struct ExprParser {
    pub(crate) tok: ExprTokenizer,
    pub(crate) cur: ExprToken,
}

Recursive-descent parser for expression filter strings.

Grammar: expr := or_expr or_expr := and_expr (“or” and_expr)* and_expr := not_expr (“and” not_expr)* not_expr := “not” not_expr | primary primary := function “(” STRING “)” | “(” expr “)” function := “glob” | “regex” | “regex_search” | “regex_match”

Fields

tok: ExprTokenizer

cur: ExprToken
