Implementation

pub fn addOne(self: *Self, gpa: Allocator) Allocator.Error!*T {
    // This can never overflow because `self.items` can never occupy the whole address space
    const newlen = self.items.len + 1;
    try self.ensureTotalCapacity(gpa, newlen);
    return self.addOneAssumeCapacity();
}
