Simple cancellation token using channels, based on the VS Code CancellationToken.

1. Add the dependency to your shard.yml:

   dependencies:
     cancellation_token:
       github: nobodywasishere/cancellation_token

2. Run shards install

require "cancellation_token"

# Create a new token source
token_source = CancellationTokenSource.new
token = token_source.token

# Spawn a fiber that checks the token to see if it should stop
spawn do
  loop do
    # Check to see if the fiber should stop
    if token.cancelled?
      break
    end

    puts "hello world"

    sleep(1.second)

    # Do fiber work here
  end
end

# Later on, if desired, cancel the token
token_source.cancel

1. Fork it (https://github.com/nobodywasishere/cancellation_token/fork)
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
