Module mark 

Types and implementations for marking spans. Diagnostic construction utilities.

The mark module provides free functions returning a [Builder], which accumulates diagnostics and is finalized into an immutable Diagnostic via [Builder::build].

Quick start

// Single error
return Err(mark::error("field `name` is required").build());

// Accumulator
let d = mark::new()
    .add(mark::error("missing `x`"))
    .add(mark::help("add `x: u32` to your struct"))
    .build();
if d.is_error() { return d.emit(); }
