Struct CPRNGEntropy

pub struct CPRNGEntropy<TPrng>where
    TPrng: PRNGenerator + CryptographicallySecure + Seedable<u128>,
{ /* private fields */ }

Expand description

Represents a generic entropy generator, which generates randomness from a cryptographically secure PRNG, but is seed from the actual OS entropy.

Implementations§

impl<TPrng> CPRNGEntropy<TPrng>
where TPrng: PRNGenerator + CryptographicallySecure + Seedable<u128>,

pub fn new() -> Result<Self, <StdEntropyGenerator as EntropyGenerator>::Error>

Creates a new instance of CPRNGEntropy

§Errors

These get propagated from StdEntropyGenerator when generating a new seed fails.

pub fn generate<T: EntropyConcreteGenerator<CPRNGEntropy<TPrng>>>( &mut self, ) -> T

Generates a new random item.
