The trait to generate random values.

Required Methods

fn next_i64(&self) -> (i64, Self)

next_i64 generates an i64 and an updated instance of Self.

fn next_i32(&self) -> (i32, Self)

next_i32 generates an i32 and an updated instance of Self.

fn next_i16(&self) -> (i16, Self)

next_i16 generates an i16 and an updated instance of Self.

fn next_i8(&self) -> (i8, Self)

next_i8 generates an i8 and an updated instance of Self.

Provided Methods

fn next_u64(&self) -> (u64, Self)

next_u64 generates a u64 and an updated instance of Self.

fn next_u32(&self) -> (u32, Self)

next_u32 generates a u32 and an updated instance of Self.

fn next_u16(&self) -> (u16, Self)

next_u16 generates a u16 and an updated instance of Self.

fn next_u8(&self) -> (u8, Self)

next_u8 generates a u8 and an updated instance of Self.

fn next_f64(&self) -> (f64, Self)

Generates an f64 in the range [0.0, 1.0) and an updated instance of Self.

Returns

• A tuple containing:
  • An f64 value in the range [0.0, 1.0)
  • An updated instance of Self

fn next_f32(&self) -> (f32, Self)

Generates an f32 in the range [0.0, 1.0) and an updated instance of Self.

Returns

• A tuple containing:
  • An f32 value in the range [0.0, 1.0)
  • An updated instance of Self

fn next_bool(&self) -> (bool, Self)

next_bool generates a bool and an updated instance of Self.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
