Struct Diagnostic 

pub struct Diagnostic {
    pub severity: Severity,
    pub code: &'static str,
    pub message: String,
    pub primary: Span,
    pub primary_label: Option<String>,
    pub labels: Vec<Label>,
    pub notes: Vec<String>,
    pub fix: Option<String>,
    pub expansion: Vec<ExpansionStep>,
}

Fields

severity: Severity

code: &'static str

A stable code (B0101) so that tests, docs and the eventual error index agree.

message: String

primary: Span

primary_label: Option<String>

labels: Vec<Label>

notes: Vec<String>

fix: Option<String>

A suggested edit. Placement ambiguity is “a compile error with a suggested annotation — never a silent guess” (§3.4), and this is where that suggestion rides.

expansion: Vec<ExpansionStep>
