Module hints 

Pre-defined DISPLAY-HINT constants for common SNMP types.

These constants can be used with Value::format_with_hint() to format values according to their MIB definitions without looking up hints.

Example

use async_snmp::format::hints;
use async_snmp::Value;
use bytes::Bytes;

let mac = Value::OctetString(Bytes::from_static(&[0x00, 0x1a, 0x2b, 0x3c, 0x4d, 0x5e]));
assert_eq!(mac.format_with_hint(hints::MAC_ADDRESS), Some("00:1a:2b:3c:4d:5e".to_string()));
