Struct Diagnostic 

pub struct Diagnostic {
    pub code: DiagCode,
    pub severity: Severity,
    pub message: String,
    pub primary: Span,
    pub labels: Vec<Label>,
    pub help: Option<String>,
    pub fixes: Vec<Fix>,
}

One located problem.

labels carries the underline text: the first label whose span equals Diagnostic::primary is rendered as the primary annotation, every other label as context. A diagnostic with no matching label still underlines the primary span, with no text.

Fields

code: DiagCode

Stable code for this message (see codes).

severity: Severity

message: String

Short summary on the error: line.

primary: Span

Where the diagnostic points.

labels: Vec<Label>

Underline text, primary label included.

help: Option<String>

fixes: Vec<Fix>
