allocation-counter

Run some Rust code while counting allocations.

Example usage:

Add as a dependency:

```toml [features] count-allocations = ["allocation-counter"]

[dependencies] allocation-counter = { version = "0", optional = true } ```

Since including the trait replaces the global memory allocator, you most likely want it gated behind a feature.

```rust

[cfg(feature = "count-allocations")]

[test]

pub fn nomemoryallocations() { let allocations = allocationcounter::count(|| { codethatshouldnotallocatememory(); }); assert_eq!(allocations, 0); } ```

You can now assert that the function does not allocate memory by running tests with the necessary feature enabled:

sh cargo test --features count-allocations
