Trait Implementations

impl Clone for List

fn clone(&self) -> List

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for List

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

impl Extend<Value> for List

fn extend<Iter: IntoIterator<Item = Value>>(&mut self, iter: Iter)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

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

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

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

Reserves capacity in a collection for the given number of additional elements.

impl From<Bag> for List

fn from(bag: Bag) -> Self

Converts to this type from the input type.

impl From<List> for Bag

fn from(list: List) -> Self

Converts to this type from the input type.

impl From<List> for Value

fn from(v: List) -> Self

Converts to this type from the input type.

impl From<Vec<Value, Global>> for List

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

Converts to this type from the input type.

impl<T> FromIterator<T> for Listwhere T: Into<Value>,

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

Creates a value from an iterator.

impl Hash for List

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 List

type Item = &'a Value

The type of the elements being iterated over.

type IntoIter = ListIter<'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 List

type Item = Value

The type of the elements being iterated over.

type IntoIter = ListIntoIterator

Which kind of iterator are we turning this into?

fn into_iter(self) -> ListIntoIterator

Creates an iterator from a value.

impl Ord for List

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<List> for List

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<List> for List

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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