pub enum Error {

    Urandom(UrandomError),
}
Expand description

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.

Initialize(InitializeError)

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

See 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.

See UrandomError.
