Function mul [src]
Multiply an elliptic curve point by a scalar.
Return error.IdentityElement if the result is the identity element.
Prototype
pub fn mul(p: Secp256k1, s_: [32]u8, endian: std.builtin.Endian) IdentityElementError!Secp256k1
Parameters
p: Secp256k1
s_: [32]u8
endian: std.builtin.Endian
Possible Errors
Source

}
