Enum MatchCond

pub enum MatchCond<K, V, R>
where
    K: Key,
    V: Value,
    R: Ref,
{
    Single(SingleCond<K, V, R>),
    And(Vec<MatchCond<K, V, R>>),
    Or(Vec<MatchCond<K, V, R>>),
    Not(Box<MatchCond<K, V, R>>),
}

A MatchCond represents a matching condition It can be a single condition or a combination of the logical operators And, Or and Not

Variants

Single(SingleCond<K, V, R>)

And(Vec<MatchCond<K, V, R>>)

Or(Vec<MatchCond<K, V, R>>)

Not(Box<MatchCond<K, V, R>>)

Trait Implementations

impl<K, V, R> Clone for MatchCond<K, V, R>

where K: Key + Clone, V: Value + Clone, R: Ref + Clone,

fn clone(&self) -> MatchCond<K, V, R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K, V, R> Debug for MatchCond<K, V, R>

where K: Key + Debug, V: Value + Debug, R: Ref + Debug,

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

Formats the value using the given formatter.

impl<K, V, R> Default for MatchCond<K, V, R>

where K: Key, V: Value, R: Ref,

fn default() -> Self

Returns the “default value” for a type.

impl<'de, K, V, R> Deserialize<'de> for MatchCond<K, V, R>

where K: Key + Deserialize<'de>, V: Value + Deserialize<'de>, R: Ref + Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<K, V, R> Display for MatchCond<K, V, R>

where K: Key, V: Value, R: Ref,

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

Formats the value using the given formatter.

impl<K, V, R> Hash for MatchCond<K, V, R>

where K: Key + Hash, V: Value + Hash, R: Ref + Hash,

fn hash<__H: Hasher>(&self, state: &mut __H)

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<K, V, R> PartialEq for MatchCond<K, V, R>

where K: Key + PartialEq, V: Value + PartialEq, R: Ref + PartialEq,

fn eq(&self, other: &MatchCond<K, V, R>) -> 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.
