Enum Person 

pub enum Person {
    First,
    Second,
    Third,
}

Grammatical person (1st, 2nd, 3rd).

Person distinguishes the speaker (1st), the listener (2nd), and everyone else (3rd). This is one of the most universal grammatical categories, appearing in nearly all human languages.

Examples by Language

Person	English	Arabic	Spanish
1st sg	I	أنا (ʾanā)	yo
2nd sg	you	أنتَ (ʾanta)	tú
3rd sg	he/she	هو/هي (huwa/hiya)	él/ella

Coreference Implications

Person is a hard constraint in coreference: “I went to the store. She bought milk” cannot have “I” and “She” coreferring (different persons).

Variants

First

First person: the speaker(s)

English: “I”, “we”, “me”, “us”, “my”, “our” Arabic: أنا (ʾanā), نحن (naḥnu)

Second

Second person: the listener(s)

English: “you”, “your”, “yours” Arabic: أنتَ/أنتِ (ʾanta/ʾanti), أنتم (ʾantum)

Third

Third person: everyone else (default for zero pronouns)

English: “he”, “she”, “it”, “they”, “him”, “her”, “them” Arabic: هو (huwa), هي (hiya), هم (hum)

This is the default because most zero pronouns in narrative text refer to third-person entities.

Implementations

impl Person

pub fn is_compatible(&self, other: &Person) -> bool

Check if this person is compatible with another for coreference.

Trait Implementations

impl Clone for Person

fn clone(&self) -> Person

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Person

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

Formats the value using the given formatter.

impl Default for Person

fn default() -> Person

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Person

fn deserialize<__D>( __deserializer: __D, ) -> Result<Person, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Person

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

Formats the value using the given formatter.

impl FromStr for Person

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Person, <Person as FromStr>::Err>

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

impl Hash for Person

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 PartialEq for Person

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Person

impl Eq for Person

impl StructuralPartialEq for Person
