Trait Implementations

impl<T: ?Sized> AsMut<T> for Ptr<T>

fn as_mut(&mut self) -> &mut T

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

impl<T: ?Sized> AsRef<T> for Ptr<T>

fn as_ref(&self) -> &T

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

impl<T: ?Sized> Clone for Ptr<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized> DafnyPrint for Ptr<T>

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

fn is_char() -> bool

impl<T: ?Sized> Debug for Ptr<T>

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

Formats the value using the given formatter.

impl<T: ?Sized> Default for Ptr<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: ?Sized> Hash for Ptr<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<T> NontrivialDefault for Ptr<T>

fn nontrivial_default() -> Self

impl<T: ?Sized, U: ?Sized> PartialEq<Ptr<U>> for Ptr<T>

fn eq(&self, other: &Ptr<U>) -> 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.
