Write back to config file. about figment HOT 3 CLOSED

Yes. Simply serialize your config structure, or the entire Figment itself, to your desired format and write it out.

@SergioBenitez , Basically std::fs::write ..etc, after dealing with string struct/serialization. I thought the crate might have a way say state.set / state.override ('path', value).

It's really rather straightforward:

let toml_string = toml::to_string_pretty(&figment)?;
std::fs::write("path.toml", &toml_string)?;

I thought the crate might have a way say state.set / state.override ('path', value).

What is state? If you serialize/deserialize into a typed structure, as encouraged by Figment, then you just need foo.path = value. If you want to work with untyped values, then simply extract into something that gives you the API you want, like serde_json::Value which lets you use pointer and pointer_mut.
