Struct ScriptedRng 

pub struct ScriptedRng { /* private fields */ }

A BattleRng that replays a fixed script of bytes, then repeats the last byte (or 0 if empty) forever.

This makes driver behaviour fully deterministic in tests: a test can pin the exact bytes the driver will observe and assert on the resulting event stream, proving turn-order ties, gates, and residuals resolve as expected.

Implementations

impl ScriptedRng

pub fn new(bytes: impl Into<Vec<u8>>) -> Self

Create a scripted RNG that yields bytes in order.

pub fn consumed(&self) -> usize

Number of bytes consumed so far. Useful for asserting draw-order parity.

Trait Implementations

impl BattleRng for ScriptedRng

fn next_u8(&mut self) -> u8

Return the next raw byte in the stream (0..=255).

fn range(&mut self, bound: u32) -> u32

Uniform integer in [0, bound).

fn chance(&mut self, num: u32, den: u32) -> bool

Coin flip succeeding with probability num / den.

impl Clone for ScriptedRng

fn clone(&self) -> ScriptedRng

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScriptedRng

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
