Struct MersenneTwisterParams 

pub struct MersenneTwisterParams {
    pub matrix_a: u32,
    pub upper_mask: u32,
    pub lower_mask: u32,
    pub tempering_mask_b: u32,
    pub tempering_mask_c: u32,
}

Parameter values for the Mersenne Twister algorithm.

The defaults match the canonical MT19937 constants. Custom parameters must satisfy the well-known invariants - see MersenneTwisterConfig::validate.

Examples

use vrd::MersenneTwisterParams;

let p = MersenneTwisterParams::default();
assert_eq!(p.matrix_a, 0x9908b0df);
assert_eq!(p.upper_mask, 0x80000000);

Fields

matrix_a: u32

Constant whose highest bit must be set (canonical: 0x9908b0df).

upper_mask: u32

Upper-bit mask (canonical: 0x80000000).

lower_mask: u32

Lower-bit mask (canonical: 0x7fffffff).

tempering_mask_b: u32

Tempering mask B (canonical: 0x9d2c5680).

tempering_mask_c: u32

Tempering mask C (canonical: 0xefc60000).

Trait Implementations

impl Clone for MersenneTwisterParams

impl Debug for MersenneTwisterParams

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

Formats the value using the given formatter.

impl Default for MersenneTwisterParams

fn default() -> Self

Returns the canonical MT19937 constants.

impl<'de> Deserialize<'de> for MersenneTwisterParams

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for MersenneTwisterParams

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 Ord for MersenneTwisterParams

fn cmp(&self, other: &MersenneTwisterParams) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MersenneTwisterParams

fn eq(&self, other: &MersenneTwisterParams) -> 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 PartialOrd for MersenneTwisterParams

fn partial_cmp(&self, other: &MersenneTwisterParams) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for MersenneTwisterParams
