Variants

Invalid(usize)

The given argument is the invalid type for the input

Missing(usize)

There is a missing input

Extra(usize)

There’s a superfluous argument

Swap(usize, usize)

Two arguments should be swapped

Permutation(Vec<Option<usize>>)

Several arguments should be reordered

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.
