Enum CharCase 

pub enum CharCase {
    Lower = 0,
    Title = 2,
    Upper = 3,
}

🔬This is a nightly-only experimental API. (titlecase #153892)

The case of a cased character, as returned by char::case.

Titlecase characters conceptually are composed of an uppercase portion followed by a lowercase portion. The variant discriminants represent this: the most significant bit represents whether the case conceptually starts as uppercase, while the least significant bit represents whether it conceptually ends as uppercase.

Variants

Lower = 0

🔬This is a nightly-only experimental API. (titlecase #153892)

Lowercase. Corresponds to the Lowercase Unicode property.

Title = 2

🔬This is a nightly-only experimental API. (titlecase #153892)

Titlecase. Corresponds to the Titlecase_Letter Unicode general category.

Upper = 3

🔬This is a nightly-only experimental API. (titlecase #153892)

Uppercase. Corresponds to the Uppercase Unicode property.

Trait Implementations

impl Clone for CharCase

fn clone(&self) -> CharCase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CharCase

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

Formats the value using the given formatter.

impl Hash for CharCase

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

where __H: Hasher,

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 CharCase

fn cmp(&self, other: &CharCase) -> 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 CharCase

fn eq(&self, other: &CharCase) -> 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 CharCase

fn partial_cmp(&self, other: &CharCase) -> 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.
