Struct ARef 

pub struct ARef<'a, T: ?Sized + 'a> { /* private fields */ }

A Ref that might not actually be borrowed. Either a Ptr (a normal & style reference), or a Ref (like from RefCell), but exposes all the methods available on Ref.

Implementations

impl<'a, T: ?Sized + 'a> ARef<'a, T>

pub fn new_ptr(x: &'a T) -> Self

Create a new ARef from a pointer.

pub fn new_ref(x: Ref<'a, T>) -> Self

Create a new ARef from a reference.

pub fn clone(orig: &Self) -> Self

See Ref.clone. Not a self method since that interferes with the Deref.

pub fn map<U: ?Sized, F>(orig: ARef<'a, T>, f: F) -> ARef<'a, U>

where F: FnOnce(&T) -> &U,

See Ref.map. Not a self method since that interferes with the Deref.

pub fn map_split<U: ?Sized, V: ?Sized, F>( orig: ARef<'a, T>, f: F, ) -> (ARef<'a, U>, ARef<'a, V>)

where F: FnOnce(&T) -> (&U, &V),

See Ref.map_split. Not a self method since that interferes with the Deref.

pub fn filter_map<U: ?Sized, F>( orig: ARef<'a, T>, f: F, ) -> Result<ARef<'a, U>, Self>

where F: FnOnce(&T) -> Option<&U>,

See Ref.filter_map. Not a self method since that interferes with the Deref.

Trait Implementations

impl<'a, T: Debug + ?Sized + 'a> Debug for ARef<'a, T>

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

Formats the value using the given formatter.

impl<T: ?Sized> Deref for ARef<'_, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: Display + ?Sized> Display for ARef<'_, T>

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

Formats the value using the given formatter.

impl<T: ?Sized> Drop for ARef<'_, T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<A: Eq + ?Sized> Eq for ARef<'_, A>

impl<T: Hash + ?Sized> Hash for ARef<'_, T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<A: Ord + ?Sized> Ord for ARef<'_, A>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<A: PartialEq<B> + ?Sized, B: ?Sized> PartialEq<ARef<'_, B>> for ARef<'_, A>

fn eq(&self, other: &ARef<'_, B>) -> bool

Equality operator ==.

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
