tuplesrecords

Tuplesrecords is a term used to describe a data type that blends features of tuples and records. In concepts and some language designs, a tuplesrecords value has a fixed length and a known sequence of element types, like a tuple, while also exposing a set of named fields that correspond to those positions, like a record. This dual representation allows both positional access and named access to the same data.

Access and representation can vary by implementation, but the core idea is that each position in the value is associated with a field name. This means you can retrieve the ith element by index or retrieve a field by its label. The association between indices and names is part of the type’s schema, and when a language provides static typing, the schema is checked at compile time. Immutability is common for such types in functional-leaning contexts, though mutable variants may exist in imperative languages.

Typing and pattern matching are typical areas where tuplesrecords are discussed. In statically typed environments, a tuplesrecords value forms a product type with named fields, enabling destructuring by position or by name in pattern matches. Dynamic languages might rely on runtime checks to ensure field-name correctness.

Use cases often involve data interchange or API design, where responses are ordered lists but also carry meaningful labels. They can facilitate transitions between purely positional data and fully named records, support interoperability between systems that prefer either representation, and aid in documenting intent through explicit field names.

Compared with plain tuples, plain records, or structs, tuplesrecords aim to combine the strengths of both while adding some complexity. Practical adoption depends on language support, tooling, and performance considerations.
