Struct djinn::Population

pub struct Population<S: Simulation, C: Redis> {
    pub conn: C,
    // some fields omitted
}

An interface to the Redis-backed agent population.

Fields

conn: C

Methods

impl<S: Simulation, C: Redis> Population<S, C>

fn new(simulation: S, conn: C) -> Population<S, C>

fn count(&self) -> usize

Count the population size.

fn world(&self) -> S::World

Get the world (state).

fn set_world(&self, world: S::World)

Set the world state.

fn get_agent(&self, id: u64) -> Option<Agent<S::State>>

Get an agent by id.

fn get_agents(&self, ids: Vec<u64>) -> Vec<Agent<S::State>>

Get agents by ids. If you need to fetch multiple agents, you should use this as it makes only one network request.

fn set_agent(&self, id: u64, state: &S::State)

Set an agent state by id.

fn set_agents(&self, updates: &Vec<(u64, &S::State)>)

Set multple agent states by ids. If you need to update multiple agents, you should use this as it makes only one network request.

fn update(&self)

Process queued updates (kill/spawn).

fn lookup(&self, index: &str) -> Vec<Agent<S::State>>

Lookup agents at a particular index.

fn random(&self, index: &str) -> Agent<S::State>

Select a random agent from an index.

fn randoms(&self, index: &str, count: usize) -> Vec<Agent<S::State>>

Select random agents from an index.

fn count_index(&self, index: &str) -> usize

Count the members of an index.

fn index(&self, index: &str, id: u64)

Add an agent (id) to an index.

fn indexes(&self, index: &str, ids: Vec<u64>)

Add agents (ids) to an index.

fn unindex(&self, index: &str, id: u64)

Remove an agent (id) from an index.

fn unindexes(&self, index: &str, ids: Vec<u64>)

Remove an agent (id) from an index.

fn reset_indices(&self)

Reset all indices.

fn reset(&self)

Reset the population; i.e. deletes all agents and updates from Redis and resets all indices.

Trait Implementations

impl<S: Clone + Simulation, C: Clone + Redis> Clone for Population<S, C>

fn clone(&self) -> Population<S, C>

Returns a copy of the value.

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

Performs copy-assignment from source.
