Enum Utf32String

pub enum Utf32String {
    Ascii(Box<str>),
    Unicode(Box<[char]>),
}

An owned version of Utf32Str.

Variants

Ascii(Box<str>)

A string represented as ASCII encoded bytes. Correctness invariant: must only contain valid ASCII (<=127)

Unicode(Box<[char]>)

A string represented as an array of unicode codepoints (basically UTF-32).

Implementations

impl Utf32String

pub fn len(&self) -> usize

Returns the number of characters in this string.

pub fn is_empty(&self) -> bool

Returns whether this string is empty.

pub fn slice(&self, range: impl RangeBounds<usize>) -> Utf32Str<'_>

Creates a slice with a string that contains the characters in the specified character range.

pub fn slice_u32(&self, range: impl RangeBounds<u32>) -> Utf32Str<'_>

Same as slice but accepts a u32 range for convenience since those are the indices returned by the matcher.

Trait Implementations

impl Clone for Utf32String

fn clone(&self) -> Utf32String

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Utf32String

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

Formats the value using the given formatter.

impl Default for Utf32String

fn default() -> Self

Returns the “default value” for a type.

impl Display for Utf32String

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

Formats the value using the given formatter.

impl From<&str> for Utf32String

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Box<str>> for Utf32String

fn from(value: Box<str>) -> Self

Converts to this type from the input type.

impl<'a> From<Cow<'a, str>> for Utf32String

fn from(value: Cow<'a, str>) -> Self

Converts to this type from the input type.

impl From<String> for Utf32String

fn from(value: String) -> Self

Converts to this type from the input type.

impl Hash for Utf32String

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Utf32String

fn cmp(&self, other: &Utf32String) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Utf32String

fn eq(&self, other: &Utf32String) -> 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 PartialOrd for Utf32String

fn partial_cmp(&self, other: &Utf32String) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
