map

Use map when you need a mutable key-value map object with explicit methods for reading keys and values.

import "std:map"

Example

import "std:map"

map users = map()
users.set("ada", 36)
log users.get("ada")

API reference

Map values

Method	Returns	Notes
value.set(k: any, v: any)	*Map	Sets a value. Keys must be comparable.
value.get(k: any)	any	Reads through the same comparable-key guard.
value.delete(k: any)	void	Deletes through the same comparable-key guard.
value.size()	number	Returns the number of stored values.
value.clear()	void	Clears all stored values.
value.getKeys()	K[]	Returns keys while preserving the map's key type.
value.getValues()	V[]	Returns values while preserving the map's value type.

Notes

• Prefer import "std:map"; the older import "osl/map" spelling remains supported.

Composite and cyclic keys are checked safely, and maps synchronize concurrent reads and writes.
