# SNMP Parser
A SNMP parser, implemented with the [nom](https://github.com/Geal/nom)
parser combinator framework.
The goal of this parser is to implement SNMP messages analysis, for example
to use rules from a network IDS.
To read a message, different functions must be used depending on the expected message
version. The main functions for parsing are [`parse_snmp_v1`](https://docs.rs/snmp-parser/latest/snmp_parser/snmp/fn.parse_snmp_v1.html),
[`parse_snmp_v2c`](https://docs.rs/snmp-parser/latest/snmp_parser/snmp/fn.parse_snmp_v2c.html) and
[`parse_snmp_v3`](https://docs.rs/snmp-parser/latest/snmp_parser/snmpv3/fn.parse_snmp_v3.html).
If you don't know the version of the message and want to parse a generic SNMP message,
use the [`parse_snmp_generic_message`](https://docs.rs/snmp-parser/latest/snmp_parser/fn.parse_snmp_generic_message.html) function.
The code is available on [Github](https://github.com/rusticata/snmp-parser)
and is part of the [Rusticata](https://github.com/rusticata) project.
