Variants

Identity

Pass the receiver as-is.

Deref

We get passed &[mut] self and call the target with *self.

This either copies self (if Self: Copy, eg. for function items), or moves out of it (for VTableShim, which effectively is passed &own Self).

RefMut

We get passed self: Self and call the target with &mut self.

In this case we need to ensure that the Self is dropped after the call, as the callee won’t do it for us.

Trait Implementations

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more

Mutably borrows from an owned value. 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.

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.
