Struct EvalContext 

pub struct EvalContext<'a> {
    pub var_name: &'a str,
    pub scope: &'a dyn Lookup,
    pub prefix: &'a [(String, Value)],
}

Per-evaluation context for context-required sources.

Carries the live kernel against which Source::Generator spec-text and Source::WorkloadParamList lookups resolve. var_name lets the source synthesise a useful error message; prefix is the prior-axis bindings the evaluator installs via PolydatKernel::materialize_subscope so dependent sources see earlier-axis values.

Fields

var_name: &'a str

The clause’s element name, for messages.

scope: &'a dyn Lookup

Where the source’s names resolve: the body’s scope with the parent’s cascaded wires.

prefix: &'a [(String, Value)]

The prior-axis bindings, in axis order.
