Trait Emitter 

pub trait Emitter: Send + Sync {
    // Required methods
    fn buffer(&self) -> Buffer;
    fn print(&self, buffer: Buffer) -> Result<(), Report>;
}

The Emitter trait is used for controlling how diagnostics are displayed.

An Emitter must produce a [Buffer] for use by the rendering internals, and its own print implementation.

When a diagnostic is being emitted, a new [Buffer] is allocated, the diagnostic is rendered into it, and then the buffer is passed to print for display by the Emitter implementation.

Required Methods

fn buffer(&self) -> Buffer

Construct a new [Buffer] for use by the renderer

fn print(&self, buffer: Buffer) -> Result<(), Report>

Display the contents of the given [Buffer]

Dyn Compatibility

This trait is dyn compatible.

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