Struct oasis_runtime_sdk::crypto::random::RootRng

pub struct RootRng { /* private fields */ }

A root RNG that can be used to derive domain-separated leaf RNGs.

Implementations

impl RootRng

pub fn new(mode: Mode) -> Self

Create a new root RNG.

pub fn invalid() -> Self

Create an invalid root RNG which will fail when any leaf RNGs are requested.

pub fn append_local_entropy(&self)

Append local entropy to the root RNG.

Non-determinism

Using this method will result in the RNG being non-deterministic.

pub fn append_tx(&self, tx_hash: Hash)

Append an observed transaction hash to RNG transcript.

pub fn append_subcontext(&self)

Append an observed subcontext to RNG transcript.

pub fn fork<C: Context + ?Sized>( &self, ctx: &C, pers: &[u8], ) -> Result<LeafRng, Error>

Create an independent leaf RNG using this RNG as its parent.
