pub struct PerformanceMiddleware { /* private fields */ }

Built-in performance monitoring middleware

Implementations

impl PerformanceMiddleware

pub fn new(slow_request_threshold: Duration) -> Self

pub fn create_default() -> Self

Create with default threshold (1 second)

pub fn with_threshold(threshold: Duration) -> Self

Create with custom threshold

Trait Implementations

impl McpMiddleware for PerformanceMiddleware

fn name(&self) -> &'static str

Name of the middleware for identification

fn priority(&self) -> i32

Priority/order of execution (lower numbers execute first)

fn after_request<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, request: &'life1 CallToolRequest, _response: &'life2 mut CallToolResult, context: &'life3 mut MiddlewareContext, ) -> Pin<Box<dyn Future<Output = McpResult<MiddlewareResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Called after the request is processed but before response is returned

fn before_request<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, request: &'life1 CallToolRequest, context: &'life2 mut MiddlewareContext, ) -> Pin<Box<dyn Future<Output = McpResult<MiddlewareResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Called before the request is processed

fn on_error<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, request: &'life1 CallToolRequest, error: &'life2 McpError, context: &'life3 mut MiddlewareContext, ) -> Pin<Box<dyn Future<Output = McpResult<MiddlewareResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Called when an error occurs during request processing
