Struct tinyset::setusize::SetUsize

pub struct SetUsize(_);

A set for usize elements.

Implementations

impl SetUsize

pub fn is_empty(&self) -> bool

Returns true if the set is empty

impl SetUsize

pub fn with_capacity_of(other: &Self) -> Self

Create an empty set with capacity to hold the provided set.

use tinyset::SetUsize;

let a: SetUsize = (1..300).collect();
let mut b = SetUsize::with_capacity_of(&a);

assert_eq!(a.capacity(), b.capacity());
assert_eq!(b.len(), 0);
for i in a.iter() {
  b.insert(i);
}
assert_eq!(a.capacity(), b.capacity());
assert_eq!(b.len(), a.len());

Create an empty set with capacity to hold the provided set.

impl SetUsize

pub fn new() -> Self

Creates an empty set..

pub fn insert(&mut self, elem: usize) -> 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.

pub fn len(&self) -> usize

Returns the number of elements in the set.

pub fn capacity(&self) -> usize

Returns the capacity of the set.

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

Returns true if the set contains a value.

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

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

pub fn iter<'a>(&'a self) -> impl Iterator<Item = usize> + 'a

Iterate

pub fn drain<'a>(&'a mut self) -> impl Iterator<Item = usize> + 'a

Drain

Trait Implementations

impl<'a, 'b> BitOr<&'b SetUsize> for &'a SetUsize

fn bitor(self, rhs: &SetUsize) -> SetUsize

Returns the union of self and rhs as a new SetUsize.

Examples

let a: tinyset::SetUsize = (1..4).collect();
let b: tinyset::SetUsize = (3..6).collect();

assert_eq!(&a | &b, (1..6).collect());

type Output = SetUsize

The resulting type after applying the | operator.

impl<'b> BitOr<&'b SetUsize> for SetUsize

fn bitor(self, rhs: &SetUsize) -> SetUsize

Returns the union of self and rhs as a new SetUsize, consuming self.

Examples

let a: tinyset::SetUsize = (1..4).collect();
let b: tinyset::SetUsize = (3..6).collect();

assert_eq!(a | &b, (1..6).collect());

type Output = SetUsize

The resulting type after applying the | operator.

impl Clone for SetUsize

fn clone(&self) -> SetUsize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SetUsize

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

Formats the value using the given formatter.

impl Default for SetUsize

fn default() -> Self

Creates an empty set..

impl FromIterator<usize> for SetUsize

fn from_iter<I: IntoIterator<Item = usize>>(iter: I) -> Self

Creates a value from an iterator.

impl IntoIterator for SetUsize

type Item = usize

The type of the elements being iterated over.

type IntoIter = IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> IntoIter

Creates an iterator from a value.

impl PartialEq<SetUsize> for SetUsize

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 !=.

impl<'a, 'b> Sub<&'b SetUsize> for &'a SetUsize

fn sub(self, rhs: &SetUsize) -> SetUsize

Returns the difference of self and rhs as a new SetUsize.

Examples

let a: tinyset::SetUsize = (1..4).collect();
let b: tinyset::SetUsize = (3..6).into_iter().collect();

assert_eq!(&a - &b, (1..3).collect());

type Output = SetUsize

The resulting type after applying the - operator.

impl<'b> Sub<&'b SetUsize> for SetUsize

fn sub(self, rhs: &SetUsize) -> SetUsize

Returns the difference of self and rhs as a new SetUsize consuming self. Should not allocate.

Examples

let a: tinyset::SetUsize = (1..4).collect();
let b: tinyset::SetUsize = (3..6).into_iter().collect();

assert_eq!(a - &b, (1..3).collect());

type Output = SetUsize

The resulting type after applying the - operator.
