Struct LeftMutator 

pub struct LeftMutator;

A mutator which always takes the left tree

Trait Implementations

impl<K, V> BinaryMutator<K, V> for LeftMutator

where V: Clone,

fn kind(&mut self) -> BinaryMutatorKind

The kind of this mutator, if it can be specially optimized

fn mutate_bin( &mut self, _key: &K, _left: &V, _right: &V, ) -> BinaryResult<Option<V>>

Mutate a value: should be the same as transform_bin, except sometimes returning UnaryResult::Left/Right when the output would be equal to the input

impl<K, L, R> BinaryTransformer<K, L, R, L> for LeftMutator

where L: Clone,

fn transform_bin(&mut self, _key: &K, left: &L, _right: &R) -> Option<L>

Transform a value pair from the input types to the output type

impl Clone for LeftMutator

fn clone(&self) -> LeftMutator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LeftMutator

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

Formats the value using the given formatter.

impl Hash for LeftMutator

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 Ord for LeftMutator

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LeftMutator

fn eq(&self, other: &LeftMutator) -> 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.

impl PartialOrd for LeftMutator

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
