Struct EvalMeta 

pub struct EvalMeta {
    pub language: String,
    pub route_id: String,
    pub step_id: String,
    pub verb: String,
    pub target: Option<String>,
}

Trusted route-level metadata describing WHERE and HOW an expression is evaluated.

All fields are compile-time configuration (operator-supplied route definitions, ADR-0032): none of them ever carry runtime exchange data.

Fields

language: String

Language the expression is written in (e.g. rhai).

route_id: String

Id of the route owning the evaluating step.

step_id: String

Id of the evaluating step.

verb: String

DSL verb that evaluates the expression (e.g. set_property).

target: Option<String>

TRUSTED compile-time destination: a property key, a header key, or body. Nested value keys inside a map are NOT part of the target — the target names the exchange slot, never data inside it.
