) -> Self
fn diagnostic_builder_emit_producing_guarantee( db: &mut DiagnosticBuilder<'_, Self> ) -> Self
Implementation of DiagnosticBuilder::emit, fully controlled by each
impl of EmissionGuarantee, to make it impossible to create a value
of Self without actually performing the emission.

handler: &Handler,
msg: impl Into<DiagnosticMessage>
