Implementations§

source§

impl Value

source

pub fn serialize<T>(value: T) -> Result<Value, Error>
where T: Serialize,

Serialize a Value from any T: Serialize.

use figment::value::{Value, Empty};

let value = Value::serialize(10i8).unwrap();
assert_eq!(value.to_i128(), Some(10));

let value = Value::serialize(()).unwrap();
assert_eq!(value, Empty::Unit.into());

let value = Value::serialize(vec![4, 5, 6]).unwrap();
assert_eq!(value, vec![4, 5, 6].into());
source

pub fn deserialize<'de, T>(&self) -> Result<T, Error>
where T: Deserialize<'de>,

Deserialize self into any deserializable T.

use figment::value::Value;

let value = Value::from("hello");
let string: String = value.deserialize().unwrap();
assert_eq!(string, "hello");
source

pub fn find(self, path: &str) -> Option<Value>

Looks up and returns the value at path path, where path is of the form a.b.c where a, b, and c are keys to dictionaries. If the key is empty, simply returns self. If the key is not empty and self or any of the values for non-leaf keys in the path are not dictionaries, returns None.

This method consumes self. See Value::find_ref() for a non-consuming variant.

§Example
use figment::{value::Value, util::map};

let value = Value::from(map! {
    "apple" => map! {
        "bat" => map! {
            "pie" => 4usize,
        },
        "cake" => map! {
            "pumpkin" => 10usize,
        }
    }
});

assert!(value.clone().find("apple").is_some());
assert!(value.clone().find("apple.bat").is_some());
assert!(value.clone().find("apple.cake").is_some());

assert_eq!(value.clone().find("apple.bat.pie").unwrap().to_u128(), Some(4));
assert_eq!(value.clone().find("apple.cake.pumpkin").unwrap().to_u128(), Some(10));

assert!(value.clone().find("apple.pie").is_none());
assert!(value.clone().find("pineapple").is_none());
source

pub fn find_ref<'a>(&'a self, path: &str) -> Option<&'a Value>

Exactly like Value::find() but does not consume self, returning a reference to the found value, if any, instead.

§Example
use figment::{value::Value, util::map};

let value = Value::from(map! {
    "apple" => map! {
        "bat" => map! {
            "pie" => 4usize,
        },
        "cake" => map! {
            "pumpkin" => 10usize,
        }
    }
});

assert!(value.find_ref("apple").is_some());
assert!(value.find_ref("apple.bat").is_some());
assert!(value.find_ref("apple.cake").is_some());

assert_eq!(value.find_ref("apple.bat.pie").unwrap().to_u128(), Some(4));
assert_eq!(value.find_ref("apple.cake.pumpkin").unwrap().to_u128(), Some(10));

assert!(value.find_ref("apple.pie").is_none());
assert!(value.find_ref("pineapple").is_none());
source

pub fn tag(&self) -> Tag

use figment::{Figment, Profile, value::Value, util::map};

let map: Value = Figment::from(("key", "value")).extract().unwrap();
let value = map.find_ref("key").expect("value");
assert_eq!(value.as_str(), Some("value"));
assert!(!value.tag().is_default());
assert_eq!(value.tag().profile(), Some(Profile::Global));

let map: Value = Figment::from(("key", map!["key2" => 123])).extract().unwrap();
let value = map.find_ref("key.key2").expect("value");
assert_eq!(value.to_i128(), Some(123));
assert!(!value.tag().is_default());
assert_eq!(value.tag().profile(), Some(Profile::Global));
source

assert_eq!(converted, Some(7.0f64));

let value: Value = Value::from(7.0f64);
assert_eq!(value.to_f64(), Some(7.0f64));
source

pub fn to_bool_lossy(&self) -> Option<bool>

Converts self to a bool if it is a Value::Bool, or if it is a Value::String or a Value::Num with a boolean interpretation.
