Trait FromConn 

pub trait FromConn:
    Send
    + Sync
    + Sized
    + 'static {
    // Required method
    fn from_conn(conn: &mut Conn) -> impl Future<Output = Option<Self>> + Send;
}

A trait to extract content from [Conn]s to be used as the second argument to an api handler. Implement this for your types.

Required Methods

fn from_conn(conn: &mut Conn) -> impl Future<Output = Option<Self>> + Send

returning None from this will not call the api handler, but will halt the conn.

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.
