Struct Scenario 

pub struct Scenario<'a> { /* private fields */ }

The representation of a scenario. A moment consisting of various events, the present actors and any predicates that apply to either.

Implementations

impl<'a> Scenario<'a>

pub fn new( actors: Vec<Actor<'a>>, thematic_relations: Vec<ThetaRoles<'a>>, properties: BTreeMap<&'a str, Vec<Entity<'a>>>, ) -> Scenario<'a>

Create a new scenario.

pub fn thematic_relations(&self) -> &[ThetaRoles<'a>]

Get the representation of all events as a slice of ThetaRoles.

pub fn properties(&self) -> &BTreeMap<&'a str, Vec<Entity<'a>>>

Get the properties (e.g. what predicates apply) of the entities in a scenario.

pub fn actors(&self) -> &[Actor<'_>]

Get a slice of all Actors in the Scenario

pub fn questions(&self) -> &[RootedLambdaPool<'a, Expr<'a>>]

Get the questions associated with a scenario (which may be empty if there are no questions). Questions are representated as RootedLambdaPool which return a truth value.

pub fn question_mut(&mut self) -> &mut Vec<RootedLambdaPool<'a, Expr<'a>>>

Get a mutable reference to the questions of a scenario. See Scenario::questions

Trait Implementations

impl<'a> Clone for Scenario<'a>

fn clone(&self) -> Scenario<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Scenario<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for Scenario<'a>

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<'a> PartialEq for Scenario<'a>

fn eq(&self, other: &Scenario<'a>) -> 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.
