Function alignForward [src]

Round an address up to the next (or current) aligned address. The alignment must be a power of 2 and greater than 0. Asserts that rounding up the address does not cause integer overflow.

Prototype

pub fn alignForward(comptime T: type, addr: T, alignment: T) T

Parameters

T: typeaddr: Talignment: T

Example

 test alignForward {
    try testing.expect(alignForward(usize, 1, 1) == 1);
    try testing.expect(alignForward(usize, 2, 1) == 2);
    try testing.expect(alignForward(usize, 1, 2) == 2);
    try testing.expect(alignForward(usize, 2, 2) == 2);
    try testing.expect(alignForward(usize, 3, 2) == 4);
    try testing.expect(alignForward(usize, 4, 2) == 4);
    try testing.expect(alignForward(usize, 7, 8) == 8);
    try testing.expect(alignForward(usize, 8, 8) == 8);
    try testing.expect(alignForward(usize, 9, 8) == 16);
    try testing.expect(alignForward(usize, 15, 8) == 16);
    try testing.expect(alignForward(usize, 16, 8) == 16);
    try testing.expect(alignForward(usize, 17, 8) == 24);
}

    assert(isValidAlignGeneric(T, alignment));
    return alignBackward(T, addr + (alignment - 1), alignment);
