Struct WhenEnv 

pub struct WhenEnv<'a> {
    pub facts: &'a FactValues,
    pub vars: &'a HashMap<String, String>,
    pub iter: Option<IterEnv<'a>>,
}

Fields

facts: &'a FactValues

vars: &'a HashMap<String, String>

iter: Option<IterEnv<'a>>

Per-iteration context, populated when this WhenEnv gates an iterated rule (for_each_dir / for_each_file / every_matching_has). None for top-level rule gating, where iter.* references resolve to falsy / null per the “unknown fact is falsy” convention.

Implementations

impl<'a> WhenEnv<'a>

pub fn new(facts: &'a FactValues, vars: &'a HashMap<String, String>) -> Self

Construct a WhenEnv without iteration context — the shape every existing call site uses. iter.* references in the expression resolve to null / false.

pub fn with_iter(self, iter: IterEnv<'a>) -> Self

Attach an iteration context. The same WhenEnv shape can then evaluate iter.path, iter.basename, and iter.has_file(...) against the supplied path + index.

Trait Implementations

impl<'a> Debug for WhenEnv<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
