Trait Random 

pub trait Random: Sized {
    // Required method
    fn try_random_from_rng<R: TryRng + ?Sized>(
        rng: &mut R,
    ) -> Result<Self, R::Error>;

    // Provided methods
    fn random_from_rng<R: Rng + ?Sized>(rng: &mut R) -> Self { ... }
    fn try_random() -> Result<Self, Error> { ... }
    fn random() -> Self { ... }
}

Random number generation support.

Required Methods

fn try_random_from_rng<R: TryRng + ?Sized>( rng: &mut R, ) -> Result<Self, R::Error>

Generate a random value.

If rng is a CSRNG, the generation is cryptographically secure as well.

Errors

• Returns R::Error in the event the RNG experienced an internal failure.

Provided Methods

fn random_from_rng<R: Rng + ?Sized>(rng: &mut R) -> Self

Generate a random value.

If rng is a CSRNG, the generation is cryptographically secure as well.

fn try_random() -> Result<Self, Error>

Randomly generate a value of this type using the system’s ambient cryptographically secure random number generator.

Errors

Returns getrandom::Error in the event the system’s ambient RNG experiences an internal failure.

fn random() -> Self

Randomly generate a value of this type using the system’s ambient cryptographically secure random number generator.

Panics

This method will panic in the event the system’s ambient RNG experiences an internal failure.

This shouldn’t happen on most modern operating systems.

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.
