Rust bindings to LLVM's SanitizerCoverage interface.

## About Rust bindings to [LLVM's `SanitizerCoverage` interface](https://clang.llvm.org/docs/SanitizerCoverage.html). Using these bindings allows you to convey additional coverage information to the `SanitizerCoverage` consumer, which is typically a fuzzer like `libFuzzer`. You can, for example, convey edge coverage information inside JIT code or which size classes are being allocated from in your custom allocator that would otherwise not be made visible by LLVM's inserted coverage instrumentation. ## Example ```rust,no_run use sancov::Counters; // Define a bunch of counters. static COUNTERS: Counters<4096> = Counters::new(); // Register the counters with the `SanitizerCoverage` consumer. COUNTERS.register(); // Increment a counter when some custom code is executed! COUNTERS[42].increment() ```
