Trait Handler 

pub trait Handler<Args>:
    Clone
    + Send
    + Sync
    + 'static {
    // Required method
    fn call(
        self,
        parts: Parts,
        body: Bytes,
    ) -> Pin<Box<dyn Future<Output = Response<BoxBody>> + Send>>;
}

A handler that can process an HTTP request and produce a response.

Implemented automatically for async functions whose arguments are extractors. The Args type parameter encodes the extractor tuple and is used for trait resolution — users don’t specify it directly.

Required Methods

fn call( self, parts: Parts, body: Bytes, ) -> Pin<Box<dyn Future<Output = Response<BoxBody>> + Send>>

Call the handler with the given request parts and pre-collected body bytes.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
