Struct Seed

pub struct Seed(/* private fields */);

Implementations

impl Seed

pub fn new(seed: u64) -> Seed

pub fn with_ts(&self, ts: u64) -> u64

pub fn with_stream(&self, axis: u64) -> u64

Stream key for a second stream axis — a per-fight draw counter, a shard index, anything that runs alongside the timestamp rather than along it.

with_ts is plain addition, so any two (seed, ts) pairs with the same sum share a stream. A second axis therefore mixes rather than adds — otherwise its key could land on the timestamp stream and replay the same rolls.

pub fn with_fight_draw(&self, n: u64) -> u64

👎Deprecated: renamed to with_stream: the mechanism is not fight-specific

pub fn rng(&self, ts: u64) -> GameRng

Draw source for the per-event stream at ts — the join between the stream keys above and GameRng, so a consumer derives per-event randomness without depending on rand itself.

Trait Implementations

impl Clone for Seed

fn clone(&self) -> Seed

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Seed

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

Formats the value using the given formatter.

impl Hash for Seed

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Seed

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
