Struct rle::ReverseSpan

pub struct ReverseSpan<S: SplitableSpan + Clone>(pub S);

A splitablespan in reverse. This is useful for making lists in descending order.

Tuple Fields

0: S

Trait Implementations

impl<S: Clone + SplitableSpan> Clone for ReverseSpan<S>

fn clone(&self) -> ReverseSpan<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug + SplitableSpan + Clone> Debug for ReverseSpan<S>

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

Formats the value using the given formatter.

impl<S: PartialEq + SplitableSpan + Clone> PartialEq<ReverseSpan<S>> for ReverseSpan<S>

fn eq(&self, other: &ReverseSpan<S>) -> bool

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

fn ne(&self, other: &ReverseSpan<S>) -> bool

This method tests for !=.

impl<S: SplitableSpan + Clone> SplitableSpan for ReverseSpan<S>

fn len(&self) -> usize

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

fn truncate(&mut self, at: usize) -> Self

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(&mut self, at: usize) -> 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 can_append(&self, other: &Self) -> 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: Self)

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.
