Available on crate feature rand_core only.

Possible errors of the methods in RandomBits trait.

Variants

RandCore(Error)

An error of the internal RNG library.

BitsPrecisionMismatch

The requested bits_precision does not match the size of the integer corresponding to the type (in the cases where this is set in compile time).

Fields

bits_precision: u32

The requested precision.

integer_bits: u32

The compile-time size of the integer.

BitLengthTooLarge

The requested bit_length is larger than bits_precision.

Fields

bit_length: u32

The requested bit length of the random number.

bits_precision: u32

The requested precision.

Trait Implementations

impl Debug for RandomBitsError

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

Formats the value using the given formatter.

impl Display for RandomBitsError

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

Formats the value using the given formatter.

impl Error for RandomBitsError

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.
