Struct PendingDiagnostic 

pub struct PendingDiagnostic {
    pub code: u32,
    pub args: Vec<DiagnosticArg>,
    pub span: Option<SourceSpan>,
    pub severity: DiagnosticSeverity,
    pub related: Vec<Self>,
}

A pending diagnostic that hasn’t been rendered yet.

This stores the structured data needed to generate an error message, but defers the expensive string formatting until rendering time.

Fields

code: u32

Diagnostic code (e.g., 2322 for type not assignable)

args: Vec<DiagnosticArg>

Arguments for the message template

span: Option<SourceSpan>

Primary source location

severity: DiagnosticSeverity

Severity level

related: Vec<Self>

Related information (additional locations)
