Trait Metrics

pub trait Metrics<Out, In>:
    Clone
    + Send
    + 'static {
    // Required methods
    fn bytes_sent(&mut self, len: usize);
    fn bytes_received(&mut self, len: usize);
    fn message_sent(&mut self, msg: &Out);
    fn message_received(&mut self, msg: &In);
}

A trait for types that observe connection metric events.

Required Methods

fn bytes_sent(&mut self, len: usize)

Callback reporting numbers of bytes sent.

fn bytes_received(&mut self, len: usize)

Callback reporting numbers of bytes received.

fn message_sent(&mut self, msg: &Out)

Callback reporting messages sent.

fn message_received(&mut self, msg: &In)

Callback reporting messages received.

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.
