Struct ActorStateModeler 

pub struct ActorStateModeler {
    pub actor_states: HashMap<ActorId, ActorState>,
    pub actor_ids_by_type: HashMap<ObjectId, Vec<ActorId>>,
    pub recently_deleted_actor_states: HashMap<ActorId, ActorState>,
}

A struct modeling the states of multiple actors at a given point in time. Provides methods to update that state with successive frames from a boxcars::Replay.

Fields

actor_states: HashMap<ActorId, ActorState>

A map of actor states with their corresponding actor ids.

actor_ids_by_type: HashMap<ObjectId, Vec<ActorId>>

A map of actor ids with their corresponding object ids.

recently_deleted_actor_states: HashMap<ActorId, ActorState>

Actor states deleted while processing the current frame.

This preserves last-known attributes long enough for code that runs after deletion, such as same-frame demolition extraction, to still inspect the removed actor.

Implementations

impl ActorStateModeler

pub fn new() -> Self

Creates a new ActorStateModeler.

Returns

A new ActorStateModeler. object.

pub fn process_frame( &mut self, frame: &Frame, frame_index: usize, ) -> SubtrActorResult<()>

Processes a frame, including handling of new, updated, and deleted actors.

Arguments

• frame - The frame to be processed.
• frame_index - The index of the frame to be processed.

Returns

An empty result (Ok(())) on success, SubtrActorError on failure.

pub fn new_actor(&mut self, new_actor: &NewActor) -> SubtrActorResult<()>

pub fn update_attribute( &mut self, update: &UpdatedAttribute, frame_index: usize, ) -> SubtrActorResult<Option<(Attribute, usize)>>

pub fn delete_actor( &mut self, actor_id: &ActorId, ) -> SubtrActorResult<ActorState>

impl Default for ActorStateModeler
