Struct BoundedRandU32 

pub struct BoundedRandU32 { /* private fields */ }

Allows sampling a u32 number in 0 .. N.

Implementations

impl BoundedRandU32

pub const _4: Self

pub const _6: Self

pub const _8: Self

pub const _10: Self

pub const _12: Self

pub const _20: Self

pub const fn new(count: u32) -> Self

Constructs a new value.

Panics

If the count is 0.

pub const fn try_new(count: u32) -> Option<Self>

Constructs a new value, or None on failure.

Failure

If the count is 0.

pub const fn count(self) -> u32

The number of possible outputs.

pub const fn place_in_range(self, val: u32) -> Option<u32>

Given a u32, try to place it into this bounded range.

Failure

• If the value is such that it doesn’t fit evenly it is rejected.

pub fn sample<F: FnMut() -> u32>(self, f: F) -> u32

Given a generator function, call it until place_in_range succeeds.

Trait Implementations

impl Clone for BoundedRandU32

fn clone(&self) -> BoundedRandU32

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoundedRandU32

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

Formats the value using the given formatter.

impl Hash for BoundedRandU32

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 BoundedRandU32

fn eq(&self, other: &BoundedRandU32) -> 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.
