Like records, tuples are a composite of other types of data. But instead of naming the components, they are identified by position. Here are some examples of tuples: (1,2,10)(true,"Hello")( [1;2;3],(0.5,'X')) A tuple with two components is called a pair. A tuple with three components is called a triple.
This document covers atomic types, such as integers and Booleans; predefined compound types, like strings and lists; and user-defined types, namely variants and records. We show how to pattern matching on those types. In OCaml, there are no type checks at runtime, and values don't change type unless explicitly converted.
16 sty 2024 · Ad 2, the latest release has tuples up to 8 components, and the next release will have up to 12 components. Since the introduction of product types in the API, it is also fairly simple for the end-user to add higher tuples if needed.
core v0.17.1 (latest): Industrial strength alternative to OCaml's standard library
In general, patterns for types with a fixed structure, like records and tuples, are irrefutable, unlike types with variable structures like lists and variants. Another important characteristic of record patterns is that they don’t need to be complete; a pattern can mention only a subset of the fields in the record.
I want to add to "acc" a tuple of 4 elements (string, int, string, int). c is a char, index a int, acc normally tuple list, patterns a string list and n a int. I have this error: first version
Tuples. Every function in OCaml takes exactly one value and returns exactly one result. For instance, our squareRoot function takes one float value and returns one float value. The advantage of always taking one argument and returning one result is that the language is extremely uniform.
