Implementations

If item is an attribute invocation, remove the attribute and return it together with its position and derives following it. We have to collect the derives in order to resolve legacy derive helpers (helpers written before derives that introduce them).

Trait Implementations

Mutable token visiting only exists for the macro_rules token marker and should not be used otherwise. Token visitor would be entirely separate from the regular visitor if the marker didn’t have to visit AST fragments in nonterminal tokens. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

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.
