Struct Context

Source

pub struct Context<'a> {
    pub root: &'a Path,
    pub index: &'a FileIndex,
    pub registry: Option<&'a RuleRegistry>,
    pub facts: Option<&'a FactValues>,
    pub vars: Option<&'a HashMap<String, String>>,
}

Expand description

Execution context handed to each rule during evaluation.

registry — available for rules that need to build and evaluate nested rules at runtime (e.g. for_each_dir). Tests that don’t exercise nested evaluation can set this to None.
facts — resolved fact values, computed once per Engine::run.
vars — user-supplied string variables from the config’s vars: section.
