Creating JSON/HTML output - Question

[quentinchambers]

Hi, I am looking through the cli trying to understand how to use stack graphs. To help with that I am trying to print out the stack graphs that I generate to better understand the structure. I see that in cli/test.rs the StackGraph instance makes a call to to_html_string. However, this method cannot be found when I try calling it directly.

I can see that it is implemented in visualization.rs. Is there some sort of way to import this that I am missing? Sorry I'm new to rust and wasn't able to find a suitable answer.

Hi @quentinchambers! The JSON (and thus HTML) output is hidden behind a feature. Using it requires adding features = ["json"] to the dependency in Cargo.toml. Might that help?

PS. Cargo docs for dependencies with features: https://doc.rust-lang.org/cargo/reference/features.html#dependency-features

Yes that helps out! Had no idea that was a thing in rust. Thanks!

I think it might be good to generate the Doc with --all-features~
