ensureTotalCapacity

If the current capacity is less than new_capacity, this function will modify the array so that it can hold at least new_capacity items. Invalidates element pointers if additional memory is needed.

Implementation

pub fn ensureTotalCapacity(self: *Self, new_capacity: usize) Allocator.Error!void {
    if (@sizeOf(T) == 0) {
        self.capacity = math.maxInt(usize);
        return;
    }

    if (self.capacity >= new_capacity) return;

    const better_capacity = Aligned(T, alignment).growCapacity(self.capacity, new_capacity);
    return self.ensureTotalCapacityPrecise(better_capacity);
}
