Cslrb

Cslrb is a gem which uses the Rust library cardano-serialization-lib to make some of its features available in Ruby.

Cardano Serialization Lib is a library, written in Rust, for serialization & deserialization of data structures used in Cardano's Haskell implementation of Alonzo along with useful utility functions.

In order to use this library you will need to have access to Rust's build tooling cargo, this simplest way to get this is via rustup.

After ensuring you have these things available, add the gem to your bundle

gem 'cslrb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cslrb

cslrb includes a Rake task which will compile the Rust library for your platform and copy it to the correct location.

For example with the method Cslrb.tx_body_from_hex which accepts a string (TX CBOR as hex):

pry(main)> cbor_hex = "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"
pry(main)> Cslrb.tx_body_from_hex(cbor_hex)
=>  "{\n  \"inputs\": [\n    {\n      \"transaction_id\": \"f97da637cc2e8b5b970b1952bcdc62422e82873bb0503a75ab70ed3c3476e9c...

Passing anything other than a String will result in an error.

Cslrb.tx_body_from_hex(cbor_hex)
Cslrb.metadata_from_output_datum(cbor_hex)

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
