use figment::{Figment, value::magic::Tagged, Jail};
use figment::providers::{Format, Toml};

#[derive(Debug, PartialEq, serde::Deserialize)]
struct Config {
    number: Tagged<usize>,

});

Implementations§

source§

impl<T> Tagged<T>

source

pub fn tag(&self) -> Tag

Returns the tag of the inner value if it is known. As long self is a leaf and was extracted from a Figment, the returned value is expected to be Some.

Example
use figment::{Figment, Profile, value::magic::Tagged};

let figment = Figment::from(("key", "value"));
let tagged = figment.extract_inner::<Tagged<String>>("key").unwrap();

assert!(!tagged.tag().is_default());
assert_eq!(tagged.tag().profile(), Some(Profile::Global));
source

pub fn into_inner(self) -> T

Consumes self and returns the inner value.

Example
use figment::{Figment, value::magic::Tagged};

let tagged = Figment::from(("key", "value"))
    .extract_inner::<Tagged<String>>("key")
    .unwrap();

let value = tagged.into_inner();
assert_eq!(value, "value");

fn fg(&self, value: Color) -> Painted<&T>

painted.fg(Color::White);
