pub fn parse_script(
    src: &str,

Expand description

This parses a text script into the AST used by Cozo.

Note! This is an unstable interface, the signature may change between releases. Depend on it at your own risk.

  • src - the script to parse

  • param_pool - the list of parameters to execute the script with. These are substituted into the syntax tree during parsing.

  • fixed_rules - a mapping of fixed rule names to their implementations. These are substituted into the syntax tree during parsing.

  • cur_vld - the current timestamp, substituted into expressions where validity is relevant.
