std

ry’s standard library is the std namespace. With the prelude on, the default, every function is also in scope by its bare name, such as List.map; with [check] prelude = false it is reachable only as std::List.map. The standard library guide covers the conventions the modules share.

Module	Functions	Summary
Result	9	A result is :Ok(value) or :Err(error), typed Result<T, E>.
List	78	Functions over R lists, typed list[T], and over Arrays.
Str	36	Functions over single strings.
Num	74	Functions over single numbers, integer or double, and eight constants (Num.pi, Num.tau, Num.e, Num.infinity and the integer and double limits).
Bool	7	Booleans are R’s TRUE and FALSE, never NA.
Dict	27	A dictionary maps keys to values, typed Dict<K, V>.
Set	22	A set of distinct keys, typed Set<T>.
