Struct Codepoints 

pub struct Codepoints(/* private fields */);

A set of Unicode codepoints

Implementations

impl Codepoints

pub fn new(src: impl IntoIterator<Item = char>) -> Self

Construct a new set of codepoints.

The input can be anything that impls IntoIterator<Item=char>, and the simplest use would be to pass an array:

let mut codepoints = Codepoints::new(['A', 'B']);

pub fn len(&self) -> usize

Return the number of codepoints.

pub fn is_empty(&self) -> bool

Returns true if there are no codepoints.

pub fn set(&mut self, codepoints: impl IntoIterator<Item = char>)

Set the codepoints. See Codepoints::new for usage.

pub fn clear(&mut self)

Remove all codepoints from the set.

pub fn contains(&self, codepoint: char) -> bool

Returns true if the provided codepoint is in this set.

pub fn insert(&mut self, codepoint: char) -> bool

Insert a codepoint into the set.

Returns true if this item did not exist in the set. If this item does exist, the order will be unchanged.

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

Iterate over the codepoints.

Trait Implementations

impl Clone for Codepoints

fn clone(&self) -> Codepoints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Codepoints

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

Formats the value using the given formatter.

impl Default for Codepoints

fn default() -> Codepoints

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Codepoints

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromIterator<char> for Codepoints

fn from_iter<T: IntoIterator<Item = char>>(iter: T) -> Self

Creates a value from an iterator.

impl<'a> IntoIterator for &'a Codepoints

type Item = &'a char

The type of the elements being iterated over.

type IntoIter = Iter<'a, char>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for Codepoints

type Item = char

The type of the elements being iterated over.

type IntoIter = IntoIter<char>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Codepoints

fn eq(&self, other: &Codepoints) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Codepoints

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Codepoints
