Struct markovian::distributions::Raw

pub struct Raw<I> { /* fields omitted */ }

Distribution over possibly infinte iterators.

Examples

With help of the raw_dist macro, we construct a random variable that samples always a fixed value.

let value = 0;
let dis = raw_dist![(1.0, value)];

assert_eq!(value, dis.sample(&mut thread_rng()));

Correctedness

Bounds on probabilities are checked only in debug mode using debug_assert. This way, there are guarantees when developing code that probabilities have valid values, but during a release run there is no overhead!

Costs

Sample cost: O(iterator length). Construction cost: O(1).

Remarks

This struct is meant to be used when one needs to sample once from an infinte iterator.
