Expand description

Parser for OR patterns in queries

Implementations§

Source§

impl DisjunctionParser

Source

pub fn parse(pattern: &str) -> Option<Disjunction>

Parse a pattern that might contain OR

Examples:

  • “(A OR B)” -> Disjunction with 2 branches
  • “(A OR B OR C)” -> Disjunction with 3 branches
  • “A” -> None (no OR, single goal)
Source

pub fn contains_or(pattern: &str) -> bool

Check if a pattern contains OR
