Struct EngineCache 

pub struct EngineCache { /* private fields */ }

Thread-safe cache of discovered engine state.

Use this to share engine discovery results across multiple clients targeting different engines.

Example

let cache = EngineCache::new();

let client1 = Client::builder("192.168.1.1:161")
    .username("admin")
    .auth(AuthProtocol::Sha1, "authpass")
    .engine_cache(cache.clone())
    .connect()
    .await?;

let client2 = Client::builder("192.168.1.2:161")
    .username("admin")
    .auth(AuthProtocol::Sha1, "authpass")
    .engine_cache(cache.clone())
    .connect()
    .await?;

Implementations

impl EngineCache

pub fn new() -> Self

Create a new empty engine cache.

pub fn get(&self, target: &SocketAddr) -> Option<EngineState>

Get cached engine state for a target.

pub fn insert(&self, target: SocketAddr, state: EngineState)

Store engine state for a target.

pub fn update_time( &self, target: &SocketAddr, response_boots: u32, response_time: u32, ) -> bool

Update time for an existing entry.

Returns true if the entry was updated, false if not found or not updated.

pub fn remove(&self, target: &SocketAddr) -> Option<EngineState>

Remove cached state for a target.

pub fn clear(&self)

Clear all cached state.

pub fn len(&self) -> usize

Get the number of cached engines.

pub fn is_empty(&self) -> bool

Check if the cache is empty.
