function u32
u32(endianness?: Endianness): Coder<number>

Creates a coder for 32-bit unsigned integers.

This function creates a coder that can encode/decode 32-bit unsigned integers (range 0-4,294,967,295). The endianness parameter determines the byte order used.

Examples

Example 1

import { assertEquals } from "@std/assert";
import { u32 } from "@hertzg/binstruct/numeric";

// Create big-endian and little-endian coders
const u32be = u32("be");
const u32le = u32("le");

// Test data
const testValue = 4294967295;

// Encode and decode with big-endian
const bufferBE = new Uint8Array(4);
const bytesWrittenBE = u32be.encode(testValue, bufferBE);
const [decodedBE, bytesReadBE] = u32be.decode(bufferBE);

assertEquals(decodedBE, testValue);
assertEquals(bytesWrittenBE, 4);
assertEquals(bytesReadBE, 4);

// Encode and decode with little-endian
const bufferLE = new Uint8Array(4);
const bytesWrittenLE = u32le.encode(testValue, bufferLE);
const [decodedLE, bytesReadLE] = u32le.decode(bufferLE);

assertEquals(decodedLE, testValue);
assertEquals(bytesWrittenLE, 4);
assertEquals(bytesReadLE, 4);

Parameters

optional
endianness: Endianness = be

The byte order to use ("be" for big-endian, "le" for little-endian), defaults to "be"

Return Type

Coder<number>

A Coder<number> for 32-bit unsigned integers

Usage

import { u32 } from "mod.ts";
