Enum Adjustment

enum Adjustment {
    Identity,
    Deref {
        source: DerefSource,
    },
    RefMut,
}

Variants

Identity

Pass the receiver as-is.

Deref

We get passed a reference or a raw pointer to 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).

Fields

source: DerefSource

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

impl Clone for Adjustment

fn clone(&self) -> Adjustment

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Adjustment

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Adjustment

fn eq(&self, other: &Adjustment) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Adjustment

impl StructuralPartialEq for Adjustment

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.
