Bump

✓ use bumpalo::Bump;

Allocates integers and strings in a bump arena without individual deallocation.

use bumpalo::Bump; let bump = Bump::new(); let x = bump.alloc(42); let y = bump.alloc("hello"); println!("{} {}", x, y);

Debug

Known issues

gotchaBump allocated memory is only freed when the Bump is dropped; long-lived allocations may waste memory.

fix

Use Bump for short-lived or phase-based allocations; consider reset() to reuse memory.
