Struct ExternalCall 

pub struct ExternalCall {
    pub func: String,
    pub arg_measures: Vec<MeasureId>,
    pub refresh_policy: RefreshPolicy,
}

A measure defined as func(arg_measures...) where func is a registered external function. Evaluated host-side per coordinate.

Fields

func: String

Name of the external function (a key in Model.external_fns).

arg_measures: Vec<MeasureId>

The measures supplying the function’s positional arguments, aligned to the function’s declared arg_types.

refresh_policy: RefreshPolicy

When this measure should be refreshed (default Manual). Advisory metadata a scheduler consults; see RefreshPolicy.
