Module handler 

Handler types and traits for SNMP MIB operations.

This module provides the interface for implementing SNMP handlers:

• MibHandler - Trait for handling GET, GETNEXT, and SET operations
• RequestContext - Information about the incoming request
• GetResult, GetNextResult, SetResult - Operation results
• OidTable - Helper for implementing GETNEXT with sorted OID storage

Example

use async_snmp::handler::{MibHandler, RequestContext, GetResult, GetNextResult, BoxFuture};
use async_snmp::{Oid, Value, VarBind, oid};

struct MyHandler;

impl MibHandler for MyHandler {
    fn get<'a>(&'a self, _ctx: &'a RequestContext, oid: &'a Oid) -> BoxFuture<'a, GetResult> {
        Box::pin(async move {
            if oid == &oid!(1, 3, 6, 1, 4, 1, 99999, 1, 0) {
                return GetResult::Value(Value::Integer(42));
            }
            GetResult::NoSuchObject
        })
    }

    fn get_next<'a>(&'a self, _ctx: &'a RequestContext, oid: &'a Oid) -> BoxFuture<'a, GetNextResult> {
        Box::pin(async move {
            let my_oid = oid!(1, 3, 6, 1, 4, 1, 99999, 1, 0);
            if oid < &my_oid {
                return GetNextResult::Value(VarBind::new(my_oid, Value::Integer(42)));
            }
            GetNextResult::EndOfMibView
        })
    }
}
