Deserializing user input

help
1

Is there a crate that allows, for lack of a better term, deserializing from stdin?

Here is an example of what I am thinking of.

#[derive(serde::Deserialize, serde::Serialize)]
pub struct GeneralSettings {
pub cookie: String,
pub proxy: String,
pub static_content: String,
}

-------------------- (Standard output, Standard Input)
Please enter information
GeneralSettings, cookie: some stuff
GeneralSettings, proxy: /asdf/
GeneralSettings, static_content: ./contents

It outputs the name of structs and struct members, prompting the user for a value for each field.

I don't know such a deserializer. I guess you could implement one. The envy deserializer for environment variables seems like something you could adapt to your purposes.

I started on some library code here.
Not the best user experience with Option types yet.
