Bars Specification 0.1.0 — Transform: map¶

Category: list · Since: 0.1.0

Projects each element to a property value.

Projects each element (a struct) to its property value, resolved via a KPointer — a bare key like "name" uses dot-notation, "/addr/city" uses an RFC 6901 pointer. Requires every element to be a struct; a non-conforming element is a soft failure yielding null.

Input coercion: list

Arguments¶

Arity: 1–1
