RecordSchema represents the declaration of a heterogeneous Record type, with Fields that are determined at runtime. A Field declares the static type of its associated values, so although the record itself is dynamic, field access is type-safe.
Given a RecordSchema declaration
schema
, any number of Records of that schema can be obtained withschema.newRecord
. The type that Scala assigns to this value is what Scala calls a "path-dependent type," meaning thatschema1.Record
andschema2.Record
name distinct types. The same is true of fields:schema1.Field[A]
andschema2.Field[A]
are distinct, and can only be used with the corresponding Record.
