# static_arena

Fixed-size bump allocator in the struct itself — **no malloc**. Stack or
`static` storage; `Option` on overflow.

```toml
[dependencies]
static_arena = "*"
stdlib = "*"
```

```cplus
import "static_arena/static_arena" as sa;
import "stdlib/option" as option;

var a: sa::StaticArena16K = sa::StaticArena16K::new();
guard let option::Option[*u8]::Some(p) = a.alloc_bytes(64usize) else {
    return;
};
```

Growing heap sibling: **`arena`**.
