Struct skyscraper::xpath::xpath_item_set::XpathItemSet

pub struct XpathItemSet<'tree> { /* private fields */ }

An ordered set of XpathItems.

Implementations

impl<'tree> XpathItemSet<'tree>

pub fn new() -> Self

Create a new empty XpathItemSet.

pub fn is_empty(&self) -> bool

Whether the set is empty.

pub fn len(&self) -> usize

The number of items in the set.

pub fn insertb(&mut self, item: XpathItem<'tree>) -> bool

Inserts a new item into the set.

Returns true if the item was inserted, false if it was already present.

pub fn insert(&mut self, item: XpathItem<'tree>)

Inserts a new item into the set.

Drops the bool returned by XpathItemSet::insertb so that it can be used in match arms without causing incompatible types with XpathItemSet::extend.

pub fn iter(&self) -> Iter<'_, XpathItem<'tree>>

Return an iterator over the items in the set.

pub fn boolean(&self) -> bool

Return the effective boolean value of the result.

🔬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<'tree> From<IndexSet<XpathItem<'tree>>> for XpathItemSet<'tree>

fn from(value: IndexSet<XpathItem<'tree>>) -> Self

Converts to this type from the input type.

impl<'tree> FromIterator<XpathItem<'tree>> for XpathItemSet<'tree>

fn from_iter<T: IntoIterator<Item = XpathItem<'tree>>>(iter: T) -> Self

Creates a value from an iterator.

impl<'tree> Index<usize> for XpathItemSet<'tree>

type Output = XpathItem<'tree>

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'a, 'tree> IntoIterator for &'a XpathItemSet<'tree>

type Item = &'a XpathItem<'tree>

The type of the elements being iterated over.

type IntoIter = Iter<'a, XpathItem<'tree>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'tree> IntoIterator for XpathItemSet<'tree>

type Item = XpathItem<'tree>

The type of the elements being iterated over.

type IntoIter = IntoIter<XpathItem<'tree>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for XpathItemSet<'_>

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 for XpathItemSet<'_>

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.
