Enum spinoso_random::Error

pub enum Error {
    Argument(ArgumentError),
    Initialize(InitializeError),
    NewSeed(NewSeedError),
    Urandom(UrandomError),
}

Sum type of all errors possibly returned from Random functions.

Random functions in spinoso-random return errors in the following conditions:

• The platform source of cryptographic randomness is unavailable.
• The platform source of cryptographic randomness does not have sufficient entropy to return the requested bytes.
• Constraints for bounding random numbers are invalid.

Variants

Argument(ArgumentError)

Error that indicates rand() was passed an invalid constraint.

See ArgumentError.

0: ArgumentError

Initialize(InitializeError)

Error that indicates that Random::new failed to generate a random seed.

See InitializeError.

0: InitializeError

NewSeed(NewSeedError)

Error that indicates that new_seed failed to generate a random seed.

See NewSeedError.

Urandom(UrandomError)

Error that indicates that urandom() failed to generate the requested random bytes from the platform source of randomness.
