Init

Initializes a hash set for use.

Module: Std::HashSet

Signature

func Init(setPtr: *HashSet);
func InitWithCap(setPtr: *HashSet, capacity: uint);

Parameters

Name	Type	Description
setPtr	*HashSet	Pointer to the set to initialize.
capacity	uint	Initial slot count (InitWithCap). Rounded up to a minimum of 16.

Description

Allocates the set's backing storage and resets its count to zero. Call this once on a fresh HashSet before any other operation. Init starts at a default capacity of 16; InitWithCap pre-sizes the set to avoid early growth.

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

WARNING

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

Example

import Std::HashSet::*;

var a: HashSet;
Init(&a);

var b: HashSet;
InitWithCap(&b, 4096u);
