Replay mock strategies. Mirrors the Python and TypeScript SDKs.

  • “none” — every child span runs real code (default)

  • “all” — every child span returns its historical output

  • “marked” — only spans declared with mock_on_replay: true return historical

    output; everything else runs real code

    block.call
  rescue => e
    begin
      warn "Bitfab: Failed to send request: #{e.message}"

def client
  @client or raise "Bitfab not configured. Call Bitfab.configure(api_key: '...') first."
end

.configure(api_key:, service_url: nil, enabled: true) ⇒ Object

Configure the global Bitfab client.

Examples:

Bitfab.configure(api_key: ENV["BITFAB_API_KEY"])

Parameters:

  • api_key (String) —

    API key for authentication

  • service_url (String, nil) (defaults to: nil) —

    base URL (default: bitfab.ai)

  @client = Client.new(api_key:, service_url:, enabled:)
end

.current_span ⇒ CurrentSpan, NoOpCurrentSpan

Get a handle to the current active span.

Call this from inside a traced method to get a span handle that allows setting metadata at runtime.

Returns:

  CurrentSpan.new(entry)
end

.current_trace ⇒ CurrentTrace, NoOpCurrentTrace

Get a handle to the current active trace.

Call this from inside a traced method to get a trace handle that allows setting trace-level context at runtime.

Returns:
