Struct breez_sdk_core::bitcoin::util::key::secp256k1::ffi::SchnorrSigExtraParams

#[repr(C)]
pub struct SchnorrSigExtraParams { /* private fields */ }
Expand description

Data structure that contains additional arguments for schnorrsig_sign_custom.

Implementations§

§

impl SchnorrSigExtraParams

pub fn new( nonce_fp: Option<unsafe extern "C" fn(_: *mut u8, _: *const u8, _: usize, _: *const u8, _: *const u8, _: *const u8, _: usize, _: *mut c_void) -> i32>, ndata: *const c_void, ) -> SchnorrSigExtraParams

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.
