Expected outcome: A library to process Tor network documents in Rust is available
Difficulty: medium
Background
Tor Metrics Library is a Java library to fetch and parse Tor descriptors.
Metrics lib provides an API in JAVA allowing processing Tor network data from the [CollecTor](https://collector.torproject.org) service for statistical analysis and for building services and applications.
Proposal
The metrics pipeline is being restructured and is slowly moving away from a mostly JAVA codebase to a rust and python tool belt.
This project would involve a complete re-implementation of the Tor metrics library in Rust.
[Metrics-lib](https://metrics.torproject.org/metrics-lib.html) is a JAVA based API that is used to parse and validate Tor network documents. The rust rewrite should provide the same parsing and validation functionalities provided by metrics-lib and in addition allow exporting of the documents in some external storage, like parquet files to be saved into object storage or a table on a postgresql database.
