Struct Diagnostic 

pub struct Diagnostic {
    pub span: SourceSpan,
    pub message: String,
    pub suggestion: Option<String>,
    pub related: Vec<RelatedInfo>,
}

Fields

span: SourceSpan

message: String

suggestion: Option<String>

related: Vec<RelatedInfo>

Secondary spans carrying supporting context (spec/error-handling.md “Spans And Labels”): a note-style related-information label pointing at a definition, prior claim, or other related site. Empty for most diagnostics; surfaced in CLI text, JSON reports, and LSP relatedInformation.

Implementations

impl Diagnostic

pub fn with_related(self, span: SourceSpan, message: impl Into<String>) -> Self

Attaches a related-information label at span (builder style, so the common no-related case stays a plain struct literal that only needs the new field defaulted).
