Struct NoiseSeed 

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

A 64-bit seed that drives all deterministic noise generators.

Construct via NoiseSeed::random() for per-session uniqueness or NoiseSeed::from(<u64>) for reproducible testing.

Example

use stygian_browser::noise::NoiseSeed;

let seed = NoiseSeed::from(12345_u64);
let seed2 = NoiseSeed::random();
assert_ne!(seed, seed2); // extremely unlikely to collide

Implementations

impl NoiseSeed

pub fn random() -> Self

Generate a process-local pseudo-random NoiseSeed.

Example

use stygian_browser::noise::NoiseSeed;
let a = NoiseSeed::random();
let b = NoiseSeed::random();
// successive calls produce different values with overwhelming probability
assert_ne!(a, b);

pub const fn as_u64(self) -> u64

Return the raw u64 seed value.

Example

use stygian_browser::noise::NoiseSeed;
let seed = NoiseSeed::from(99_u64);
assert_eq!(seed.as_u64(), 99);

Trait Implementations

impl Clone for NoiseSeed

fn clone(&self) -> NoiseSeed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoiseSeed

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NoiseSeed

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NoiseSeed

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

Formats the value using the given formatter.

impl From<u64> for NoiseSeed

fn from(v: u64) -> Self

Converts to this type from the input type.

impl Hash for NoiseSeed

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

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 NoiseSeed

fn eq(&self, other: &NoiseSeed) -> 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.

impl Serialize for NoiseSeed

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
