Implementations

impl RateLimitMiddleware

pub fn new(requests_per_minute: u32, burst_limit: u32) -> Self

Create a new rate limiting middleware

pub fn with_limits(requests_per_minute: u32, burst_limit: u32) -> Self

Create with custom limits

pub fn default() -> Self

Create with default limits (60 requests per minute, burst of 10)

Trait Implementations

impl McpMiddleware for RateLimitMiddleware

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

Name of the middleware for identification

fn priority(&self) -> i32

Priority/order of execution (lower numbers execute first)

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 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 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
