isInfinity property

@override bool get isInfinity

Checks if the Edwards curve point represents the point at infinity.

This method checks whether the Edwards curve point represents the point at infinity, which is defined as either an empty set of coordinates or having both x and y coordinates equal to zero.

Returns:

• true if the point is the point at infinity, false otherwise.

Implementation

@override
bool get isInfinity =>
    _coords.isEmpty ||
    (_coords[0] == BigInt.zero || _coords[3] == BigInt.zero);
