Init

Initializes a hash map for use.

Module: Std::HashMap

Signature

func Init(mapPtr: *HashMap);
func InitWithCap(mapPtr: *HashMap, capacity: uint);

Parameters

Name	Type	Description
mapPtr	*HashMap	Pointer to the map to initialize.
capacity	uint	Initial slot count (InitWithCap). Rounded up to a minimum of 16.

Description

Allocates the map's backing storage and resets its count to zero. Call this once on a fresh HashMap before any other operation. Init starts at a default capacity of 16 slots; InitWithCap lets you pre-size the map to avoid early growth when you know roughly how many entries you'll store.

These are module-level functions that take a pointer to the map, so call them as Init(&map) rather than as methods.

WARNING

Always pair initialization with Free to release the map's memory.

Example

import Std::HashMap::*;

var a: HashMap;
Init(&a);                    // default capacity

var b: HashMap;
InitWithCap(&b, 1024u);      // pre-sized for ~1000 entries
