Implementations§

source§

impl SchnorrSigExtraParams

source

pub fn new(nonce_fp: SchnorrNonceFn, ndata: *const c_void) -> Self

Create a new SchnorrSigExtraParams properly initialized.

nonce_fp: pointer to a nonce generation function. If NULL rustsecp256k1_v0_5_0_nonce_function_bip340 is used

ndata: pointer to arbitrary data used by the nonce generation function (can be NULL). If it is non-NULL and rustsecp256k1_v0_5_0_nonce_function_bip340 is used, then ndata must be a pointer to 32-byte auxiliary randomness as per BIP-340.
