figment_string
Forces data parsed by a figment::Provider
to be parsed as a string. See this GitHub issue and the figment::Providers::Env
documentation for some background.
Ever see this error?
% env NAME=8080 cargo run
Error: invalid type: found unsigned int `8080`, expected a string for key "NAME"
in environment variable(s)
Well, now you can do this, and it will work even with numbers or booleans or whatever as input:
# use figment::{Figment, providers::Env};
# use serde::Deserialize;
#[derive(Deserialize)]
struct Config {
#[serde(deserialize_with = "figment_string::deserialize_as_string")]
name: String,
}
fn main() {
temp_env::with_var("NAME", Some("8080"), || {
let config: Config = Figment::new()
.merge(figment::providers::Env::raw())
.extract()
.unwrap();
println!("Hello, {}!", config.name);
});
}
