pub enum SecureRandomError {
    Argument(ArgumentError),
    RandomBytes(RandomBytesError),
    Memory(TryReserveError),
}
Expand description

Sum type of all errors possibly returned from random_bytes.

random_bytes can return errors under several conditions:

  • The given byte length is not a valid usize.
  • The underlying source of randomness returns an error when generating the requested random bytes.

Variants

Argument(ArgumentError)

Error that indicates an argument parsing or value logic error occurred.

See ArgumentError.

RandomBytes(RandomBytesError)

Error that indicates the underlying source of randomness failed to generate the requested random bytes.

See RandomBytesError.

Memory(TryReserveError)

Error that indicates an error was received from the memory allocator.

This may mean that too many random bytes were requested or the system is out of memory.

See TryReserveError and TryReserveErrorKind for more information.
