Trait Implementations

impl<T: Hashable> Hashable for HashableWrapper<T>

type Output = T::Output

fn hashed(&self) -> T::Output

A well-distributed integer derived from the data.

impl<T: Ord + Hashable> HashOrdered for HashableWrapper<T>

impl<T: PartialOrd + Hashable> PartialOrd<HashableWrapper<T>> for HashableWrapper<T> where
    T::Output: PartialOrd, 

fn partial_cmp(&self, other: &HashableWrapper<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &HashableWrapper<T>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &HashableWrapper<T>) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &HashableWrapper<T>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &HashableWrapper<T>) -> bool

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

impl<T: Copy + Hashable> Copy for HashableWrapper<T> where
    T::Output: Copy, 

impl<T: PartialEq + Hashable> PartialEq<HashableWrapper<T>> for HashableWrapper<T> where
    T::Output: PartialEq, 

fn eq(&self, other: &HashableWrapper<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &HashableWrapper<T>) -> bool

This method tests for !=.

impl<T: Default + Hashable> Default for HashableWrapper<T> where
    T::Output: Default, 

fn default() -> HashableWrapper<T>

Returns the "default value" for a type.

impl<T: Hashable> From<T> for HashableWrapper<T>

fn from(item: T) -> HashableWrapper<T>

Performs the conversion.

impl<T: Clone + Hashable> Clone for HashableWrapper<T> where
    T::Output: Clone, 

fn clone(&self) -> HashableWrapper<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Ord + Hashable> Ord for HashableWrapper<T> where
    T::Output: Ord, 

fn cmp(&self, other: &HashableWrapper<T>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

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

Returns max if self is greater than max, and min if self is less than min. Otherwise this will return self. Panics if min > max.

impl<T: Eq + Hashable> Eq for HashableWrapper<T> where
    T::Output: Eq, 

impl<T: Debug + Hashable> Debug for HashableWrapper<T> where
    T::Output: Debug, 

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

Formats the value using the given formatter.

impl<T: Hashable> Deref for HashableWrapper<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: Hashable + Abomonation> Abomonation for HashableWrapper<T>

unsafe fn entomb<W: Write>(&self, write: &mut W) -> Result<()>

Write any additional information about &self beyond its binary representation.

unsafe fn exhume<'a, 'b>(
    &'a mut self,
    bytes: &'b mut [u8]
) -> Option<&'b mut [u8]>

Recover any information for &mut self not evident from its binary representation.

fn extent(&self) -> usize

Reports the number of further bytes required to entomb self.
