Module bounded 

A port of my bounded_alloc module from Monadic Bot. Unlike the original, this one is more tightly bound to the closures it is used with. Also unlike the original, this one does not rely on undefined behavior. By default, that is. There are two ways to make this bounded allocator useful:

• Rely on std library UB and make alloc() unwind
• Rely on a Nightly feature and set an unwinding alloc_error_hook

There is a secret CFG option for the first thing, and you can do the second thing yourself like:

#![feature(alloc_error_hook)]
use ::std::alloc::{Layout, set_alloc_error_hook};
fn your_alloc_error_hook(layout: Layout) {
   panic!("memory allocation of {} bytes failed", layout.size());
}
::std::alloc::set_alloc_error_hook(your_alloc_error_hook);

In either case, the with_max_alloc macro simplifies basic usage by performing the catch_unwind for you.

Macros

with_max_alloc

Run a task with a statically known bound on allocation.

Structs

Bounded

A Store wrapper which provides an allocation limit on top of whatever allocator it is given.
