Enum rand_mt::RecoverRngError

#[non_exhaustive]pub enum RecoverRngError {
    TooFewSamples(usize),
    TooManySamples(usize),
}

Error returned from fallible Mersenne Twister recovery constructors.

When the std feature is enabled, this type implements std::error::Error.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooFewSamples(usize)

Attempted to recover an RNG with too many samples.

Recover constructors require an exact number of samples to ensure the recovered RNG matches the state of the RNG that supplied all of the samples.

TooManySamples(usize)

Attempted to recover an RNG with too few samples.

Too few samples leaves the internal state buffer partially uninitialized.

Recover constructors require an exact number of samples to ensure the recovered RNG matches the state of the RNG that supplied all of the samples.

impl Eq for RecoverRngError

impl Error for RecoverRngError

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

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