pub struct GRLParser;

GRL (Grule Rule Language) Parser Parses Grule-like syntax into Rule objects

Implementations

impl GRLParser

pub fn parse_rule(grl_text: &str) -> Result<Rule>

Parse a single rule from GRL syntax

Example GRL syntax:

rule CheckAge "Age verification rule" salience 10 {
    when
        User.Age >= 18 && User.Country == "US"
    then
        User.IsAdult = true;
        Retract("User");
}

pub fn parse_rules(grl_text: &str) -> Result<Vec<Rule>>

Parse multiple rules from GRL text

pub fn parse_with_modules(grl_text: &str) -> Result<ParsedGRL>

Parse GRL text with module support

Example:

defmodule SENSORS {
  export: all
}

defmodule CONTROL {
  import: SENSORS (rules * (templates temperature))
}

rule "CheckTemp" {
  when temperature.value > 28
  then println("Hot");
}
