Enum artichoke_backend::extn::stdlib::securerandom::SecureRandomError

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

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.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
