Trait Implementations

impl<'arena, T: Clone> Clone for Sequence<'arena, T>

fn clone(&self) -> Sequence<'arena, T>

Returns a duplicate of the value.

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

impl<'arena, T: Debug> Debug for Sequence<'arena, T>

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

Formats the value using the given formatter.

impl<'arena, T: Hash> Hash for Sequence<'arena, T>

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<'arena, T> Index<usize> for Sequence<'arena, T>

type Output = T

The returned type after indexing.

fn index(&self, index: usize) -> &T

Performs the indexing (container[index]) operation.

impl<'a, T> IntoIterator for &'a Sequence<'_, T>

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = Iter<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'arena, T> IntoIterator for Sequence<'arena, T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<'arena, <Sequence<'arena, T> as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'arena, T: Ord> Ord for Sequence<'arena, T>

fn cmp(&self, other: &Sequence<'arena, T>) -> 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<'arena, T: PartialEq> PartialEq for Sequence<'arena, T>

fn eq(&self, other: &Sequence<'arena, T>) -> 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<'arena, T: PartialOrd> PartialOrd for Sequence<'arena, T>

fn partial_cmp(&self, other: &Sequence<'arena, T>) -> 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.

impl<'arena, T> Serialize for Sequence<'arena, T>

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
