Struct r_gen::trace::Choicemap

pub struct Choicemap { /* fields omitted */ }

A struct to hold all of the random choices made during the execution of a generative model.

Implementations

impl Choicemap

pub fn new() -> Choicemap

Create a new, blank choice map.

Example

use r_gen::trace::Choicemap; 
use r_gen::distributions::Value; 
let mut choicemap = Choicemap::new(); 
choicemap.add_choice("p", Value::Real(0.5)); 

pub fn from(choices: Vec<(&str, Value)>) -> Choicemap

Create a new choicemap with given choices in it.

Example

use r_gen::trace::Choicemap; 
use r_gen::distributions::Value; 
let mut choicemap = Choicemap::from(vec![("p", Value::Real(0.5))]); 

pub fn add_choice(&mut self, identifier: &str, value: Value)

Add a choice to this choicemap.

Example

use r_gen::trace::Choicemap; 
use r_gen::distributions::Value; 
let mut choicemap = Choicemap::new(); 
choicemap.add_choice("p", Value::Real(0.5)); 

pub fn get_choices(&self) -> Vec<(&str, Value)>

Get a list of the choices that were made in the generative model.

pub fn contains_key(&self, key: &str) -> bool

Check whether or not the given key is already in the choicemap.
