A no_std bump allocator over an arbitrary region of memory. Can
be used to pass objects up the stack when it would otherwise be
inconvenient; for instance, if the objects are dynamically sized.
```rust use bump_into::{self, BumpInto};
// allocate 64 bytes of uninitialized space on the stack let mut bumpintospace = bumpinto::space!(64); let bumpinto = BumpInto::new(&mut bumpintospace[..]);
// allocating an object produces a mutable reference with
// the same lifetime as the BumpInto instance, or None
// if there isn't enough space
let number: &mut u64 = bumpinto
.allocwith(|| 123)
.expect("not enough space");
asserteq!(*number, 123);
*number = 50000;
asserteq!(*number, 50000);
// slices can be allocated as well let slice: &mut [u16] = bumpinto .allocnwith(5, core::iter::repeat(10)) .expect("not enough space"); asserteq!(slice, &[10; 5]); slice[2] = 100; assert_eq!(slice, &[10, 10, 100, 10, 10]); ```
