Struct Multiset 

pub struct Multiset { /* private fields */ }

A bag’s contents: each distinct value, sorted, and how many times it’s in the bag (never zero). A sorted vector rather than a map: bags are small, copied whenever they change, and compared each time worlds merge, which is fastest in contiguous memory.

Implementations

impl Multiset

pub fn new(counts: BTreeMap<Value, u64>) -> Multiset

From counts, leaving out zeros.

pub fn iter(&self) -> impl Iterator<Item = (&Value, &u64)> + Clone

pub fn keys(&self) -> impl Iterator<Item = &Value> + Clone

pub fn values(&self) -> impl Iterator<Item = &u64> + Clone

pub fn get(&self, v: &Value) -> Option<&u64>

How many times v is in the bag, if it is.

pub fn without_nth(&self, i: usize) -> Multiset

The bag without one of its i-th distinct value.

pub fn without(&self, v: &Value) -> Option<Multiset>

The bag without one v, if it has one.

Trait Implementations

impl Clone for Multiset

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Multiset

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

Formats the value using the given formatter.

impl Default for Multiset

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Multiset

impl Hash for Multiset

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 Multiset

fn cmp(&self, other: &Multiset) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Multiset

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Multiset

fn partial_cmp(&self, other: &Multiset) -> 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.
