Interface NarrowingFunction

A function whose result is bounded by one argument (e.g. match.arg by its choices), classified by that argument alone.

interface NarrowingFunction {
    argIdx?: number;
    argName?: string;
    call: Identifier;
}

Properties

argIdx?: number

the index of the bounding argument; omit (with argName) for an always-DerivedConstant result

argName?: string

the name of the bounding argument; omit (with argIdx) for a result that is always a bounded, content-independent value
