fn from(v: Bag) -> Self

Converts to this type from the input type.

impl From<HashSet<Value>> for Bag

fn from(values: HashSet<Value>) -> Self

fn from(list: List) -> Self

Converts to this type from the input type.

impl From<Vec<Value>> for Bag

fn from(values: Vec<Value>) -> Self

Converts to this type from the input type.

impl<T> FromIterator<T> for Bag

where T: Into<Value>,

fn from_iter<I: IntoIterator<Item = T>>(iter: I) -> Bag

Creates a value from an iterator.

impl Hash for Bag

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<'a> IntoIterator for &'a Bag

type Item = &'a Value

The type of the elements being iterated over.

type IntoIter = BagIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for Bag

type Item = Value

The type of the elements being iterated over.

type IntoIter = BagIntoIterator

Which kind of iterator are we turning this into?

fn into_iter(self) -> BagIntoIterator

Creates an iterator from a value.

impl Ord for Bag

fn cmp(&self, other: &Self) -> 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 Bag

fn eq(&self, other: &Self) -> 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 Bag

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

fn pretty_doc<'b, D, A>(&'b self, arena: &'b D) -> DocBuilder<'b, D, A>

where D: DocAllocator<'b, A>, D::Doc: Clone, A: Clone,

impl Eq for Bag
