Implementations

impl VerbClass

pub fn is_stative(&self) -> bool

Returns true if this is a stative verb class (no change of state).

States denote properties or relations that hold without change: “know”, “love”, “exist”.

pub fn is_durative(&self) -> bool

Returns true if this verb class denotes events with duration.

Durative events: States, Activities, and Accomplishments all have temporal extent. Non-durative: Achievements and Semelfactives are punctual.

pub fn is_telic(&self) -> bool

Returns true if this verb class has an inherent endpoint (telic).

Telic events: Accomplishments and Achievements reach a natural endpoint. Atelic events: States, Activities, and Semelfactives have no inherent endpoint.

Trait Implementations

impl Clone for VerbClass

fn clone(&self) -> VerbClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VerbClass

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

Formats the value using the given formatter.

impl Default for VerbClass

fn default() -> VerbClass

Returns the “default value” for a type.

impl Hash for VerbClass

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 VerbClass

fn eq(&self, other: &VerbClass) -> 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.
