types: constants and types related to the Hare type system

The types module provides access to some information about the Hare type system. It provides constants like INT_MAX, which defines the useful range for integer types (see math:: for f32 and f64 limits), as well as types like slice, which describe the internal structure of data types like slices and str.

Types

type floating[permalink] [source]

type floating = (f32 | f64);

A tagged union of all floating point numeric types.

type integer[permalink] [source]

type integer = (...signed | ...unsigned);

A tagged union of all integer types, excluding uintptr.

type numeric[permalink] [source]

type numeric = (...integer | ...floating);

A tagged union of all numeric types, excluding uintptr.

type signed[permalink] [source]

type signed = (i8 | i16 | i32 | i64 | int);

A type representing the internal structure of slices, useful for low-level slice manipulation.

type string[permalink] [source]

type string = struct {
	// UTF-8 encoded octets.
