Enum 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.

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.

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<ArgumentError> for Error

fn from(err: ArgumentError) -> Self

Converts to this type from the input type.

impl From<InitializeError> for Error

fn from(err: InitializeError) -> Self

Converts to this type from the input type.

impl From<NewSeedError> for Error

fn from(err: NewSeedError) -> Self

Converts to this type from the input type.

impl From<UrandomError> for Error

fn from(err: UrandomError) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Error

fn partial_cmp(&self, other: &Error) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
