  • final class RecordSchema extends AnyRef

    RecordSchema represents the declaration of a heterogeneous Record type, with Fields that are determined at runtime.

    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 with schema.newRecord. The type that Scala assigns to this value is what Scala calls a "path-dependent type," meaning that schema1.Record and schema2.Record name distinct types. The same is true of fields: schema1.Field[A] and schema2.Field[A] are distinct, and can only be used with the corresponding Record.

sealed trait Field[A] extends AnyRef

Field is a handle used to access some corresponding value in a Record. A field may also declare a default, which is computed for each record it is associated with, at most once per record instance.
