Struct ScriptedRng 

pub struct ScriptedRng { /* private fields */ }

A RandomSource that returns a fixed list of rolls, in order. For tests that need an exact trace of rolls. Percent rolls and roll_below draws come from two separate lists.

Implementations

impl ScriptedRng

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

Returns rolls one by one. Each must be in 0..=99.

pub fn with_below(self, draws: impl Into<Vec<u32>>) -> Self

Also returns draws, one by one, from roll_below.

pub fn consumed(&self) -> usize

How many percent rolls have been taken so far.

pub fn consumed_below(&self) -> usize

How many roll_below draws have been taken so far.

Trait Implementations

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.

impl Default for ScriptedRng

fn default() -> ScriptedRng

Returns the “default value” for a type.

impl Eq for ScriptedRng

impl PartialEq for ScriptedRng

fn eq(&self, other: &ScriptedRng) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl RandomSource for ScriptedRng

fn roll_percent(&mut self) -> u8

Panics

When the script is used up: the test expected fewer rolls.

fn roll_below(&mut self, n: u32) -> u32

Panics

When the draws are used up, or the next one isn’t below n: the test expected other draws.
