Trait GmailStream 

pub trait GmailStream:
    Read
    + Write
    + Send
    + Any {
    // Required method
    fn as_any_mut(&mut self) -> &mut dyn Any;
}

Available on crate feature client only.

Boxable client stream: Read + Write + Send plus Any so callers can downcast back to the concrete stream type.

Required Methods

fn as_any_mut(&mut self) -> &mut dyn Any

Returns the stream as a mutable Any for downcasting.

Dyn Compatibility

This trait is dyn compatible.

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