Struct OrderedSet 

pub struct OrderedSet { /* private fields */ }

A type wrapping indexmap::IndexSet

Implementations

impl OrderedSet

pub fn new() -> Self

Creates a new empty OrderedSet.

pub fn with_capacity(capacity: usize) -> Self

Creates a new empty OrderedSet with the specified capacity.

pub fn full_len(&self) -> usize

Return the number of elements in the set, including empty elements.

Computes in O(1) time.

pub fn len(&self) -> usize

Return the number of elements in the set.

Computes in O(1) time.

pub fn is_empty(&self) -> bool

Returns true if the set contains no elements.

Computes in O(1) time.

pub fn add(&mut self, value: JsValue) -> bool

Insert a value pair in the set.

If an equivalent value already exists in the set, returns false leaving original value in the set and without altering its insertion order.

If no equivalent value existed in the set, returns true and inserts the new value at the end of the set.

Computes in O(1) time (amortized average).

pub fn delete(&mut self, value: &JsValue) -> bool

Delete the value from the set and return true if successful

Return false if value is not in set.

Computes in O(n) time (average).

pub fn clear(&mut self)

Removes all elements in the set, while preserving its capacity.

pub fn contains(&self, value: &JsValue) -> bool

Checks if a given value is present in the set

Return true if value is present in set, false otherwise.

Computes in O(n) time (average).

pub fn get_index(&self, index: usize) -> Option<&JsValue>

Get a key-value pair by index Valid indices are 0 <= index < self.len() Computes in O(1) time.

pub fn iter(&self) -> impl Iterator<Item = &JsValue>

Return an iterator over the values of the set, in their order

Trait Implementations

impl Clone for OrderedSet

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderedSet

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

Formats the value using the given formatter.

impl Default for OrderedSet

fn default() -> Self

Returns the “default value” for a type.

impl Finalize for OrderedSet

fn finalize(&self)

Cleanup logic for a type.

impl JsData for OrderedSet

impl Trace for OrderedSet

unsafe fn trace(&self, tracer: &mut Tracer)

Marks all contained Gcs.

unsafe fn trace_non_roots(&self)

Trace handles located in GC heap, and mark them as non root.

fn run_finalizer(&self)

Runs Finalize::finalize on this object and all contained subobjects.
