#[non_exhaustive]pub struct ConstModifiers {
pub defaultness: Option<Default>,
}Expand description
Additional optional information about a const item.
This data structure may grow to accommodate future Rust language changes.
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.defaultness: Option<Default>Unstable syntax: RFC 1210 “Impl specialization”
