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 Ord for Condition

fn cmp(&self, other: &Condition) -> Ordering

This method returns an Ordering between self and other.

impl PartialEq for Condition

fn eq(&self, other: &Condition) -> bool

Tests for self and other values to be equal, and is used by ==.

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