Struct snarkvm_parameters::testnet3::powers::PowersOfBetaG

pub struct PowersOfBetaG<E: PairingEngine> { /* private fields */ }

Implementations

impl<E: PairingEngine> PowersOfBetaG<E>

pub fn num_powers(&self) -> usize

Returns the number of contiguous powers of beta G starting from the 0-th power.

pub fn available_powers(&self) -> (Range<usize>, Range<usize>)

Returns the range of powers of beta G. In detail, it returns the range of the available “normal” powers of beta G, i.e. the contiguous range of powers of beta G starting from G, and, the range of shifted_powers.

For example, if the output of this function is (0..8, 24..32), then self contains the powers

• beta^0 * G, beta^1 * G, ..., beta^7 * G, and
• beta^24 * G, ..., beta^31 * G.

pub fn download_powers_for(&mut self, range: &Range<usize>) -> Result<()>
