Struct david_set::CastSet

pub struct CastSet<T: Cast> { /* fields omitted */ }

A set implemented for types that can be cast to usize

Methods

impl<T: Cast> CastSet<T>

fn new() -> CastSet<T>

Creates an empty set..

fn with_capacity(cap: usize) -> CastSet<T>

Creates an empty set with the specified capacity.

fn len(&self) -> usize

Returns the number of elements in the set.

fn reserve(&mut self, additional: usize)

Reserves capacity for at least additional more elements to be inserted in the set. The collection may reserve more space to avoid frequent reallocations.

fn insert(&mut self, elem: T) -> bool

Adds a value to the set.

If the set did not have this value present, true is returned.

If the set did have this value present, false is returned.

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

Returns true if the set contains a value.

fn remove(&mut self, value: &T) -> bool

Removes an element, and returns true if that element was present.

fn iter(&self) -> Iter<T>

Returns an iterator over the set.

fn drain(&mut self) -> IntoIter<T>

Clears the set, returning all elements in an iterator.

Trait Implementations

impl<T: Debug + Cast> Debug for CastSet<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<T: Clone + Cast> Clone for CastSet<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Cast> IntoIterator for &'a CastSet<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) -> Iter<'a, T>

Creates an iterator from a value.
