Function std::alloc::realloc 1.28.0[−][src]
pub unsafe fn realloc(ptr: *mut u8, layout: Layout, new_size: usize) -> *mut u8
Reallocate memory with the global allocator.
This function forwards calls to the GlobalAlloc::realloc method
of the allocator registered with the #[global_allocator] attribute
if there is one, or the std crate’s default.
This function is expected to be deprecated in favor of the realloc method
of the Global type when it and the Alloc trait become stable.
