Implementations§

Source§

impl SubdiagnosticVariant

Source

pub(super) fn from_attr( attr: &Attribute, fields: &IndexMap<String, (Ident, TokenStream)>, used_fields: &mut HashSet<Ident>, ) -> Result<Option<SubdiagnosticVariant>, DiagnosticDeriveError>

Constructs a SubdiagnosticVariant from a field or type attribute such as #[note], #[error("add parenthesis")] or #[suggestion(code = "...")]. Returns the SubdiagnosticKind and the diagnostic message, if specified.
