Function arrow::alloc::reallocate[−][src]

pub unsafe fn reallocate<T: NativeType>(
    ptr: NonNull<T>, 
    old_size: usize, 
    new_size: usize
) -> NonNull<T>
Expand description

Safety

This function is unsafe because undefined behavior can result if the caller does not ensure all of the following:

  • ptr must be currently allocated via this allocator,

  • new_size must be greater than zero.

  • new_size, when rounded up to the nearest multiple of ALIGNMENT, must not overflow (i.e., the rounded value must be less than usize::MAX).
