Trait Implementations

impl<T> Clone for Single<T>

where T: Clone,

fn clone(&self) -> Single<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Single<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for Single<T>

where T: Default,

fn default() -> Single<T>

Returns the “default value” for a type.

impl<T> HasLength for Single<T>

fn len(&self) -> usize

The number of child items in the entry. This is indexed with the size used in truncate.

fn is_empty(&self) -> bool

impl<T> Hash for Single<T>

where T: Hash,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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<T> MergableSpan for Single<T>

where T: Clone,

fn can_append(&self, _other: &Single<T>) -> bool

See if the other item can be appended to self. can_append will always be called immediately before append.

fn append(&mut self, _other: Single<T>)

Merge the passed item into self. Essentially, self = self + other.

fn prepend(&mut self, other: Self)

Append an item at the start of this item. self = other + self.

impl<T> PartialEq for Single<T>

where T: PartialEq,

fn eq(&self, other: &Single<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<T> SplitableSpanCtx for Single<T>

where T: Clone,

type Ctx = ()

fn truncate_ctx( &mut self, _at: usize, _ctx: &<Single<T> as SplitableSpanCtx>::Ctx, ) -> Single<T>

Split the entry, returning the part of the entry which was jettisoned. After truncating at pos, self.len() == pos and the returned value contains the rest of the items.

fn truncate_keeping_right_ctx(&mut self, at: usize, ctx: &Self::Ctx) -> Self

The inverse of truncate. This method mutably truncates an item, keeping all content from at..item.len() and returning the item range from 0..at.

fn split_ctx(self, at: usize, ctx: &Self::Ctx) -> (Self, Self)

impl<T> Copy for Single<T>

where T: Copy,

impl<T> Eq for Single<T>

where T: Eq,

impl<T> StructuralPartialEq for Single<T>
