Struct differential_dataflow::hashable::OrdWrapper

pub struct OrdWrapper<T: Ord + Hashable> {
    pub item: T,
}

A wrapper around hashable types that ensures an implementation of Ord that compares hash values first.

Fields

item: T

The item, so you can grab it.

Trait Implementations

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

impl<T: Clone + Ord + Hashable> Clone for OrdWrapper<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Eq + Ord + Hashable> Eq for OrdWrapper<T>

impl<T: PartialEq + Ord + Hashable> PartialEq for OrdWrapper<T>

fn eq(&self, __arg_0: &OrdWrapper<T>) -> bool

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

fn ne(&self, __arg_0: &OrdWrapper<T>) -> bool

This method tests for !=.

impl<T: Debug + Ord + Hashable> Debug for OrdWrapper<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

impl<T: Default + Ord + Hashable> Default for OrdWrapper<T>

fn default() -> OrdWrapper<T>

Returns the "default value" for a type.

impl<T: Ord + Hashable> PartialOrd for OrdWrapper<T>

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

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

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

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

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

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

impl<T: Ord + Hashable> Ord for OrdWrapper<T>

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

impl<T: Ord + Hashable> Hashable for OrdWrapper<T>

type Output = T::Output
