Write back to config file.

[uwejan]

been using configrs for multiple project, and now with a new project writing back to the config file is required. configs.toml
Was wondering if this crate is able of doing so.
Thank you.

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.

Thank you for pairing in here with me. I am About to digg more into it. More info please. Does that preserve comments?

state just a metaform of the file contents, and yes its in toml format, i know i can use toml-edit for and it does preserve comments, but am looking for less boilerplate.
