Expand description
Macro expansion information associated with a diagnostic.
Fields (Non-exhaustive)
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.span: DiagnosticSpan
span where macro was applied to generate this code; note that
this may itself derive from a macro (if
span.expansion.is_some()
)
macro_decl_name: String
name of macro that was applied (e.g., “foo!” or “#[derive(Eq)]”)
def_site_span: Option<DiagnosticSpan>
span where macro was defined (if known)
