true upon success, false if memory could not be reallocated. In the
latter case arr[$ - delta .. $] is left with default-initialized elements.
TypedAllocator.shrinkArray
bool shrinkArray(T)(ref T[] arr, size_t delta)Shrinks an array by delta elements using allocatorFor!(T[]).
If arr.length < delta, does nothing and returns false. Otherwise, destroys the last arr.length - delta elements in the array and then reallocates the array's buffer. If reallocation fails, fills the array with default-initialized data.
Parameters
T | element type of the array being created |
arr | a reference to the array being shrunk |
delta | number of elements to remove (upon success the new length of arr is arr.length - delta) |
Returns
Throws
The first two overloads throw only if the used allocator's primitives do.
The overloads that involve copy initialization deallocate memory and propagate the exception if the copy operation throws.
