Trait Implementations

impl<K: Clone> Clone for DictionaryCol<K>

fn clone(&self) -> DictionaryCol<K>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug> Debug for DictionaryCol<K>

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

Formats the value using the given formatter.

impl<K: PartialEq> PartialEq for DictionaryCol<K>

fn eq(&self, other: &DictionaryCol<K>) -> 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.
