Module format 

Formatting utilities for SNMP values.

This module provides formatting functions for converting raw SNMP data into human-readable strings.

Display Hints

The display_hint module implements RFC 2579 DISPLAY-HINT formatting for OCTET STRING values. This is commonly used to format MAC addresses, IP addresses, and other structured binary data.

use async_snmp::format::display_hint;

// Format a MAC address
let mac = display_hint::apply("1x:", &[0x00, 0x1a, 0x2b, 0x3c, 0x4d, 0x5e]);
assert_eq!(mac, "00:1a:2b:3c:4d:5e");

// Format an IPv4 address
let ip = display_hint::apply("1d.1d.1d.1d", &[192, 168, 1, 1]);
assert_eq!(ip, "192.168.1.1");

Hex Encoding

The hex module provides hexadecimal encoding and decoding utilities.

use async_snmp::format::hex;

// Encode bytes to hex string
assert_eq!(hex::encode(&[0xde, 0xad, 0xbe, 0xef]), "deadbeef");

// Lazy formatting for logging
let data = [0x00, 0xff];
println!("{}", hex::Bytes(&data)); // prints: 00ff
