 ## Metadata format
 
-The benchmark name in the `cargo` benchmarks can be provided as a `,`-separated string where each item represents a key-value pair with the format `key=value`, e.g. `category=ML-KEM,keySize=44,name=PK Validation,platform=neon,api=unpacked`. Additionally, one of these separators may be a `/`, where the left-hand side represents the keys configured for a Criterion group. In that case, the right-hand side represents the keys for a benchmark function on that group, e.g. `category=ML-KEM,keySize=44,name=PK Validation/platform=neon,api=unpacked`. Aside from this separator, no other `/` characters should be included in the name.

 Alternatively, the benchmark name can be provided as a simple string, which will then be set as the value of the `name` key. This will only happen if there are no `key=value` pairs found in the benchmark name.
