Struct VirtualOffset

pub struct VirtualOffset { /* private fields */ }

Follows the OpenZeppelin’s ERC4626 mitigation strategy for inflation attack. Using a “virtual” offset to +1 to both total shares and assets representing the virtual total shares and virtual total assets. A donation of 1 and under will be completely captured by the vault—without affecting the user. A donation greater than 1, the attacker will suffer loss greater than the user.
