operator - method
- int offset
A pointer to the offsetth T before this one.
Equivalent to this + (-offset).
Returns a pointer to the T whose address is
offset times the size of T before the address of this pointer.
That is, (this - offset).address == this.address - offset * sizeOf<T>().
Also, (this - offset).value is equivalent to this[-offset],
and similarly for setting,
Implementation
external Pointer<T> operator -(int offset);
