interface VariantTable.NonEmpty<R,C,V>

A non-empty type-variant immutable Table of row key type R, column key type C, and value type V. In the Table, a combination of a row and column key has exactly one value. See the Table documentation and the VariantTable API documentation

Type parameters

Rthe row key type
Cthe column key type
Vthe value type

Type-variance means that both the key and value types can be widened in a type-safe way without casting. @note As a consequence of being variant, the type does not contain methods that (can) add new elements to the collection.
