Integrations

config

adotenv-config exposes document values as a config source.

use adotenv_config::AdotenvSource;

let doc = adotenv::parse_strict("host=localhost\nport=8080\n").unwrap();
let config = config::Config::builder()
    .add_source(AdotenvSource::from_document(&doc))
    .build()?;

The adapter follows config key rules: names are case-insensitive and dots create nested paths. Its load feature adds from_environment for LoadedEnvironment.

config can deserialize typed structures with its own scalar coercion.

Figment

adotenv-figment exposes a Profile::Default dictionary with original key spelling.

use adotenv_figment::AdotenvProvider;

let doc = adotenv::parse_strict("host=localhost\nport=8080\n").unwrap();
let figment = figment::Figment::new().merge(AdotenvProvider::from_document(&doc));

Figment values remain strings. Deserialize string fields and convert explicitly.

The load feature adds from_environment for loaded environments.

Shared rules

Both adapters use the document or environment’s duplicate policy, lookup participation and bare-key behavior. They do not expand references, read files or mutate the process environment.
