Implementations

impl RExprRuntime

pub fn new() -> Self

pub fn eval(&self, expr: &str, arg: &Value) -> Result<Value, Error>

eval express with arg value,if cache have value it will no run lexer expr.

pub fn eval_no_cache(
    &self,
    lexer_arg: &str,
    arg: &Value
) -> Result<Value, Error>

no cache mode to run engine

pub fn parse(&self, lexer_arg: &str) -> Result<Node, Error>

parse get node
