Struct javarandom::JavaRandom

pub struct JavaRandom { /* private fields */ }

Rust implementation of the java.util.Random class.

Implementations

impl JavaRandom

pub fn new() -> JavaRandom

Creates a new JavaRandom instance with a random seed.

pub fn with_seed(seed: i64) -> JavaRandom

Creates a new JavaRandom instance with a given seed.

Examples found in repository

examples/basic.rs (line 4)

fn main() {
    let mut rnd = JavaRandom::with_seed(123);

    for i in 0..10 {
        println!("{i:<0}: {}", rnd.next_int());
    }
}

pub fn set_seed(&mut self, seed: i64)

Set the seed of this JavaRandom instance. This is identical to creating a new instance with the given seed.

pub fn seed(&self) -> i64

Get the seed of this JavaRandom instance.

pub fn next_bytes(&mut self, bytes: &mut Vec<u8>)

Replace the content of bytes with the next random bytes.

pub fn next_int(&mut self) -> i32

Get a random i32 from this JavaRandom instance

For generating a random int with a bound, see [next_int_with_bound]

examples/basic.rs (line 7)

fn main() {
    let mut rnd = JavaRandom::with_seed(123);

    for i in 0..10 {
        println!("{i:<0}: {}", rnd.next_int());
    }
}

pub fn next_int_with_bound(&mut self, bound: u32) -> i32

Get a random i32 from this JavaRandom instance with a bound

pub fn next_long(&mut self) -> i64

Get a random i64 from this JavaRandom instance.

pub fn next_boolean(&mut self) -> bool

Get a random bool from this JavaRandom instance.

pub fn next_float(&mut self) -> f32

Get a random f32 from this JavaRandom instance

pub fn next_double(&mut self) -> f64

Get a random f64 from this JavaRandom instance.

Trait Implementations

impl Clone for JavaRandom

fn clone(&self) -> JavaRandom

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JavaRandom

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

Formats the value using the given formatter.

impl Default for JavaRandom

fn default() -> JavaRandom

Returns the “default value” for a type.

impl Hash for JavaRandom

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 JavaRandom

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for JavaRandom

impl StructuralPartialEq for JavaRandom
