async_snmp/handler/mod.rs
1//! Handler types and traits for SNMP MIB operations.
2//!
3//! This module provides the interface for implementing SNMP handlers:
4//!
5//! - [`MibHandler`] - Trait for handling GET, GETNEXT, and SET operations
6//! - [`RequestContext`] - Information about the incoming request
7//! - [`GetResult`], [`GetNextResult`], [`SetResult`] - Operation results
8//! - [`OidTable`] - Helper for implementing GETNEXT with sorted OID storage
9//!
10//! # Example
11//!
12//! ```rust
13//! use async_snmp::handler::{MibHandler, RequestContext, GetResult, GetNextResult, BoxFuture};
14//! use async_snmp::{Oid, Value, VarBind, oid};
15//!
16//! struct MyHandler;
17//!
18//! impl MibHandler for MyHandler {
19//! fn get<'a>(&'a self, _ctx: &'a RequestContext, oid: &'a Oid) -> BoxFuture<'a, GetResult> {
20//! Box::pin(async move {
21//! if oid == &oid!(1, 3, 6, 1, 4, 1, 99999, 1, 0) {
22//! return GetResult::Value(Value::Integer(42));
23//! }
24//! GetResult::NoSuchObject
25//! })
26//! }
27//!
28//! fn get_next<'a>(&'a self, _ctx: &'a RequestContext, oid: &'a Oid) -> BoxFuture<'a, GetNextResult> {
29//! Box::pin(async move {
30//! let my_oid = oid!(1, 3, 6, 1, 4, 1, 99999, 1, 0);
31//! if oid < &my_oid {
32//! return GetNextResult::Value(VarBind::new(my_oid, Value::Integer(42)));
33//! }
34//! GetNextResult::EndOfMibView
35//! })
36//! }
37//! }
38//! ```
