Formats the value using the given formatter.

impl<P: Pool> Deref for Box<P>

type Target = <P as Pool>::Item

The resulting type after dereferencing.

fn deref(&self) -> &P::Item

Dereferences the value.

impl<P: Pool> DerefMut for Box<P>

fn deref_mut(&mut self) -> &mut P::Item

Mutably dereferences the value.

impl<P: Pool> Display for Box<P>

where P::Item: Display,

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

Formats the value using the given formatter.

impl<P: Pool> Drop for Box<P>

fn drop(&mut self)

Executes the destructor for this type.

impl<P: Pool> Hash for Box<P>

where P::Item: Hash,

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

where H: Hasher,

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<P: Pool> Ord for Box<P>

where P::Item: Ord,

fn cmp(&self, rhs: &Box<P>) -> 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.

where Self: Sized,

Restrict a value to a certain interval.

impl<P: Pool> PartialEq for Box<P>

where P::Item: PartialEq,

fn eq(&self, rhs: &Box<P>) -> 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.

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.
