[−][src]Crate boxing_arena
The boxing-arena
crate provides a very simply reuse of Box
allocation by
keeping a vector of reusable Box
allocations that can be used when wanting to
wrap a value in Box
.
It would be sometimes easier to introduce boxing-arena
in code bases where
Box
is already used extensively than to use some other arena crate that
affects type and life-time semantics more drastically.
Basic usage demonstration:
use boxing_arena::BoxingArena; // Prepare a long-lived arena: let mut ba = BoxingArena::new(); // ... per allocation ... : let big_value = [0u8; 0x1000]; // Instead of using `Box::new` directly, we do: let boxed_big_value = ba.rebox(big_value); // NOTE: Type of boxed_big_value is Box<[0u8; 0x1000]> // Instead of letting Rust drop and deallocate the Box, we do: ba.unbox(boxed_big_value);
