stackFallback
Returns a StackFallbackAllocator allocating using either a
FixedBufferAllocator on an array of size size and falling back to
fallback_allocator if that fails.

- pageSize
- If the page size is comptime-known, return value is comptime.
- defaultQueryPageSize
- The default implementation of `std.options.queryPageSize`.
- stackFallback
- Returns a `StackFallbackAllocator` allocating using either a
- StackFallbackAllocator
- An allocator that attempts to allocate using a
- testAllocator
- This one should not try alignments that exceed what C malloc can handle.
TODO Utilize this on Windows.
Values
- next_mmap_addr_hint
- TODO Utilize this on Windows.
- page_size_min
- comptime-known minimum page size of the target.
- page_size_max
- comptime-known maximum page size of the target.
- c_allocator
- Supports the full Allocator interface, including alignment, and exploiting
- raw_c_allocator
- Asserts allocations are within `@alignOf(std.c.max_align_t)` and directly
- page_allocator
- On operating systems that support memory mapping, this allocator makes a

- = .{ .ptr = undefined, .vtable = &SmpAllocator.vtable, }
- wasm_allocator
- This allocator is fast, small, and specific to WebAssembly.
