}

Variants

All

All predicates may be implied by the trait.

SelfOnly

Only traits that reference Self: .. are implied by the trait.

SelfThatDefines(Ident)

Only traits that reference Self: .. and define an associated type with the given ident are implied by the trait.

SelfAndAssociatedTypeBounds

Only traits that reference Self: .. and their associated type bounds. For example, given Self: Tr<A: B>, this would expand to Self: Tr and <Self as Tr>::A: B.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
