Function load 

pub fn load<T: DeserializeOwned>(spec: &LoadSpec<'_>) -> Result<T, Error>

Reads and deserializes a configuration section.

This is what the generated load() calls. Missing files are skipped; everything else — a parse failure, a missing required field, a value that cannot become the requested type — is an Error naming the key path and the source it came from.

Errors

See ErrorKind for the categories.

Example

use dynamic_config::{load, Format, LoadSpec, Source};
use serde::Deserialize;

#[derive(Deserialize)]
struct Server { port: u16 }

let sources = [Source::inline(r#"{"server": {"port": 8080}}"#, Format::Json)];
let server: Server = load(&LoadSpec::new("server", &sources).with_env("APP_"))
    .expect("the inline document is well formed");

assert_eq!(server.port, 8080);
