Trait Filter 

pub trait Filter: Sized {
    // Required method
    fn is_match(&self, ip: IpAddr) -> bool;

    // Provided method
    fn or<F2: Filter>(self, right: F2) -> Or<Self, F2> { ... }
}

Interface to define function that filters out IP address

When match is found, IP address is skipped from being selected as client’s IP (e.g. it is load balancer IP)

Required Methods

fn is_match(&self, ip: IpAddr) -> bool

Returns true if ip matches

Provided Methods

fn or<F2: Filter>(self, right: F2) -> Or<Self, F2>

Combines self with right filter in OR operation

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.
