Struct DefaultCommonality

pub struct DefaultCommonality(/* private fields */);

A commonality based on the Default trait.

Important: This type’s implementation of Commonality is valid only if T::default() == T::default(). Any type with a valid Eq implementation satisfies this requirement, but many types like f64 and Vec<f64> also satisfy this requirement, despite not implementing Eq.

A TotalHashMap or TotalBTreeMap using this commonality only stores entries with non-default values.

Trait Implementations

impl<T: PartialEq + Default> Commonality<T> for DefaultCommonality

fn common() -> T

The common value of type V.

fn is_common(value: &T) -> bool

Returns true if value is the common value of type V. Self::is_common(Self::common()) must be true.
