Implementations

impl SentenceBreak

pub fn of(ch: char) -> SentenceBreak

Find the character Sentence_Break property value.

Trait Implementations

impl CharProperty for SentenceBreak

fn prop_abbr_name() -> &'static str

The abbreviated name of the property.

fn prop_long_name() -> &'static str

The long name of the property.

fn prop_human_name() -> &'static str

The human-readable name of the property.

impl Clone for SentenceBreak

fn clone(&self) -> SentenceBreak

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SentenceBreak

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

Formats the value using the given formatter.

impl Default for SentenceBreak

fn default() -> Self

Returns the “default value” for a type.

impl Display for SentenceBreak

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

Formats the value using the given formatter.

impl EnumeratedCharProperty for SentenceBreak

fn all_values() -> &'static [SentenceBreak]

Exhaustive list of all property values.

fn abbr_name(&self) -> &'static str

The abbreviated name of the property value.

fn long_name(&self) -> &'static str

The long name of the property value.

fn human_name(&self) -> &'static str

The human-readable name of the property value.

impl FromStr for SentenceBreak

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for SentenceBreak

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 PartialEq for SentenceBreak

fn eq(&self, other: &SentenceBreak) -> 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 TotalCharProperty for SentenceBreak

fn of(ch: char) -> Self

The property value for the character.

impl Copy for SentenceBreak

impl Eq for SentenceBreak

impl StructuralPartialEq for SentenceBreak
