It started as a port of raven-ruby, and ended up as a partial rewrite of it, still supporting most of its features and public API.
Only thing missing from its Ruby equivalent is source fetching, which in compiled language like Crystal is impossible without actually embedding the source into the binary - not something anyone would want
Any testing and help with development would be appreciated.
Would be great if this lib could be included on the Sentry Integrations page - if deemed appropriate.
Cheers and thanks for building Sentry in the first place!
