Implementations

impl<T> MCPCacheMiddleware<T>

where T: Clone + Serialize + for<'de> Deserialize<'de> + Send + Sync + 'static,

pub fn new(config: &MCPCacheConfig) -> Self

Create a new MCP cache middleware

pub fn new_default() -> Self

Create a new middleware with default configuration

pub async fn execute_tool<F, Fut>( &self, tool_name: &str, parameters: HashMap<String, Value>, tool_executor: F, ) -> Result<T>

where F: FnOnce(HashMap<String, Value>) -> Fut, Fut: Future<Output = Result<T>>,

Execute a tool with caching

Errors

This function will return an error if:

• Tool execution fails
• Cache operations fail
• Serialization/deserialization fails

pub fn get_cached_result( &self, tool_name: &str, parameters: &HashMap<String, Value>, ) -> Option<T>

Get a cached result without executing the tool

pub fn invalidate_tool(&self, tool_name: &str)

Invalidate cache entries for a specific tool

pub fn invalidate_all(&self)

Invalidate all cache entries

pub fn get_stats(&self) -> MCPCacheStats

Get cache statistics

pub fn get_cache_size(&self) -> usize
