Trait Exchange 

pub trait Exchange {
    // Required method
    fn exchange<'life0, 'life1, 'async_trait>(
        &'life0 mut self,
        command: &'life1 [u8],
        timeout: Duration,
    ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, Error>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Exchange trait provides a low-level interface for byte-wise exchange of APDU commands with a ledger devices

Required Methods

fn exchange<'life0, 'life1, 'async_trait>( &'life0 mut self, command: &'life1 [u8], timeout: Duration, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, Error>> + Send + 'async_trait>>

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

Dyn Compatibility

This trait is dyn compatible.

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