Trait Handler 

pub trait Handler: Send + Sync {
    // Required method
    fn handle<'life0, 'async_trait>(
        &'life0 self,
        request: Request,
    ) -> Pin<Box<dyn Future<Output = Result<Response>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Handler trait for processing requests.

This is the core abstraction - all request handlers implement this trait. Handlers receive a request and produce a response or an error.

Required Methods

fn handle<'life0, 'async_trait>( &'life0 self, request: Request, ) -> Pin<Box<dyn Future<Output = Result<Response>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Handles an HTTP request and produces a response.

Errors

Returns an error if the request cannot be processed.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<T: Handler + ?Sized> Handler for Arc<T>

Blanket implementation for Arc<T> where T: Handler.

This allows Arc<dyn Handler> to be used as a Handler, enabling shared ownership of handlers across threads.

fn handle<'life0, 'async_trait>( &'life0 self, request: Request, ) -> Pin<Box<dyn Future<Output = Result<Response>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,
