Enum Style 

pub enum Style {
    Severity(Severity),
    Code,
    Caret(Severity),
    Location,
    Dim,
}

The semantic styles a diagnostic uses. Each maps to zero or more SGR codes. Keeping these semantic (rather than Red/Bold) lets the whole palette be retuned in one place.

Variants

Severity(Severity)

The error/warning/note/help label and the message in the header.

Code

The diagnostic code, e.g. [Y001].

Caret(Severity)

The caret run underlining a span, in the severity’s color.

Location

The path:line:col location and the | gutter — dimmed.

Dim

Backtrace frame numbers (#0) in the crash debugger — dimmed.
