type_info #146922)Expand description
Compile-time type information about unions.
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.generics: &'static [Generic]🔬This is a nightly-only experimental API. (
type_info #146922)Instantiated generics of the union.
fields: &'static [Field]🔬This is a nightly-only experimental API. (
type_info #146922)All fields of the union.
