Struct RegisterStateRef 

pub struct RegisterStateRef<'a>(/* private fields */);

A reference to the register state saved when an exception happened.

Implementations

impl RegisterStateRef<'_>

pub unsafe fn get_mut(&mut self) -> &mut RegisterState

Returns a mutable reference to the register state.

Safety

Any changes made to the saved register state made via this reference must not cause undefined behaviour when returning from the exception.

Exactly what this means depends on the exception and the context in which it happened, but for example changing the ELR to point to an invalid or unexpected location, or changing some general-purpose register value which the code doesn’t expect to change could cause undefined behaviour.

Trait Implementations

impl AsRef<RegisterState> for RegisterStateRef<'_>

fn as_ref(&self) -> &RegisterState

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<RegisterState> for RegisterStateRef<'_>

fn borrow(&self) -> &RegisterState

Immutably borrows from an owned value.

impl<'a> Debug for RegisterStateRef<'a>

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

Formats the value using the given formatter.

impl Deref for RegisterStateRef<'_>

type Target = RegisterState

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> PartialEq for RegisterStateRef<'a>

fn eq(&self, other: &RegisterStateRef<'a>) -> 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.
