Struct ShuffledRng 

pub struct ShuffledRng {
    entries: Vec<bool>,
    position: usize,
}

A shuffled finite deck containing a fixed number of successful entries.

Fields

entries: Vec<bool>

position: usize

Implementations

impl ShuffledRng

pub fn new(success_entries: u32, total_entries: u32) -> Option<Self>

pub fn from_valid_counts(success_entries: u32, total_entries: u32) -> Self

Constructs a deck whose counts were validated by the authoring boundary.

Panics

Panics when the deck is empty or contains more successes than entries.

pub fn reset(&mut self)

pub fn trigger(&mut self, rng: &mut dyn FnMut() -> f64) -> bool

Draws the next entry, shuffling a fresh deck after exhaustion.

Panics

Panics only if the private deck-position invariant is violated.
