Trait Host 

pub trait Host: Send {
    // Required methods
    fn exit(
        &mut self,
        status: Result<(), ()>,
    ) -> impl Future<Output = Result<()>> + Send;
    fn exit_with_code(
        &mut self,
        status_code: u8,
    ) -> impl Future<Output = Result<()>> + Send;
}

Required Methods

fn exit( &mut self, status: Result<(), ()>, ) -> impl Future<Output = Result<()>> + Send

Exit the current instance and any linked instances.

fn exit_with_code( &mut self, status_code: u8, ) -> impl Future<Output = Result<()>> + Send

Exit the current instance and any linked instances, reporting the specified status code to the host.

The meaning of the code depends on the context, with 0 usually meaning “success”, and other values indicating various types of failure.

This function does not return; the effect is analogous to a trap, but without the connotation that something bad has happened.

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.

Exit the current instance and any linked instances, reporting the specified status code to the host.
