Trait Writer 

pub trait Writer {
    // Required method
    fn write(&self, f: &mut Formatter<'_>) -> Result;
}

A trait for types that can be written into a string.

This works very similarly to Debug, and is automatically implemented if Debug is implemented for a type. It is also implemented for any writable type inside a Mutex.

The derived implementation of Debug may change between Rust versions, so if stability is key for your use case, please implement Writer explicitly instead.

Required Methods

fn write(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Dyn Compatibility

This trait is dyn compatible.

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