Hi there! I wrote a tool to visualize cargo build plans as Gantt charts. Support for build plan output landed as an unstable option in cargo nightly within the last month. I don’t think Gantt charts are the perfect visualization here, but they’re better than any other option I’ve come up with so far. Note that the timing information in the chart is fictional–build actions are assigned a start time purely based on their dependency chain, and all actions are given a “1 second” duration. Also note that cargo build plans are by definition target-specific–they represent the exact set of actions that cargo would run for a specific build.
Try it out and see what you think!
