Trait ReadMessage 

pub trait ReadMessage {
    // Required methods
    fn pop_erased(&mut self) -> Option<Erased>;
    fn try_pop<M: Debug + 'static>(&mut self) -> Option<M>;
    fn try_peek<M: Debug + 'static>(&self) -> Option<&M>;
    fn peek_debug(&self) -> Option<&dyn Debug>;
}

This trait allows peeking and popping messages from the stack

Required Methods

fn pop_erased(&mut self) -> Option<Erased>

Pop a type-erased message from the stack, if non-empty

fn try_pop<M: Debug + 'static>(&mut self) -> Option<M>

Try popping the last message from the stack with the given type

fn try_peek<M: Debug + 'static>(&self) -> Option<&M>

Try observing the last message on the stack without popping

fn peek_debug(&self) -> Option<&dyn Debug>

Debug the last message on the stack, if any

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.
