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 parse(s: &'a str) -> Result<Self, ScenarioParsingError>

Parses a scenario from a string.

let s = "<a (Red), b, c (Blue, Red); {(Green)}, {A: a}, {P: c (Blue)}> lambda a x pa_Blue(x); lambda a x pa_Red(x)";
let scenario = Scenario::parse(s).unwrap();
assert_eq!(scenario.to_string(), s);

Errors

Will return an error if the Scenario is incorrectly formatted.

impl<'a> Scenario<'a>

pub fn all_scenarios( actors: &[Actor<'a>], event_kinds: &[PossibleEvent<'a>], actor_properties: &[&'a str], max_number_of_events: Option<usize>, max_number_of_actors: Option<usize>, max_number_of_properties: Option<usize>, ) -> ScenarioIterator<'a>

Returns a ScenarioIterator which goes over all possible scenarios with the provided actors and event descriptions

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<'a>]

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<'de: 'a, 'a> Deserialize<'de> for Scenario<'a>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Scenario<'_>

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.

impl<'a> Serialize for Scenario<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
