pub fn handle_alloc_error(layout: Layout) -> !
Abort on memory allocation error or failure.
Callers of memory allocation APIs wishing to abort computation in response to an allocation error are encouraged to call this function, rather than directly invoking panic! or similar.
The default behavior of this function is to print a message to standard error and abort the process. It can be replaced with set_alloc_error_hook and take_alloc_error_hook.
