Struct RandomBytesError

pub struct RandomBytesError { /* private fields */ }

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

This error is typically returned by the operating system.

Implementations

impl RandomBytesError

pub const fn new() -> Self

Construct a new, default random bytes error.

Examples

const ERR: RandomBytesError = RandomBytesError::new();
assert_eq!(ERR.message(), "OS Error: Failed to generate random bytes");

pub const fn message(self) -> &'static str

Retrieve the exception message associated with this random bytes error.

Examples

let err = RandomBytesError::new();
assert_eq!(err.message(), "OS Error: Failed to generate random bytes");

Trait Implementations

impl Clone for RandomBytesError

fn clone(&self) -> RandomBytesError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RandomBytesError

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

Formats the value using the given formatter.

impl Default for RandomBytesError

fn default() -> RandomBytesError

Returns the “default value” for a type.

impl Display for RandomBytesError

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

Formats the value using the given formatter.

impl Error for RandomBytesError

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<Error> for RandomBytesError

fn from(_: Error) -> Self

Converts to this type from the input type.

impl From<RandomBytesError> for Error

fn from(err: RandomBytesError) -> Self

Converts to this type from the input type.

impl Hash for RandomBytesError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RandomBytesError

fn cmp(&self, other: &RandomBytesError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RandomBytesError

fn eq(&self, other: &RandomBytesError) -> 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 RandomBytesError

fn partial_cmp(&self, other: &RandomBytesError) -> 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.
