Struct Config 

pub struct Config { /* private fields */ }

The application’s configuration tree.

Cloning is cheap: every clone shares one store, so a handler can hold a Config without copying the tree.

Implementations

impl Config

pub fn new() -> Self

pub fn with_defaults() -> Self

Seed the tree with the framework’s defaults, honouring .env.

pub fn load_dir(&self, dir: impl AsRef<Path>) -> Result<()>

Load every config/*.json file, keyed by file stem.

config/app.json becomes the app.* namespace, mirroring Laravel’s config/app.php. String values support ${VAR} interpolation so a config file can defer to .env.

pub fn set(&self, path: &str, value: impl Into<Json>)

Set (or replace) a value at a dotted path.

pub fn merge(&self, namespace: &str, value: Json)

Merge an object into a namespace, keeping keys that are not overridden.

pub fn get(&self, path: &str) -> Option<Json>

Look up a dotted path: config.get("app.name").

pub fn string(&self, path: &str, default: &str) -> String

pub fn int(&self, path: &str, default: i64) -> i64

pub fn list(&self, path: &str) -> Vec<String>

A list, from either a JSON array or one comma-separated string.

The string form exists because of .env: a variable can only hold a string, so CORS_ALLOWED_ORIGINS=https://a.example,https://b.example has to mean the same as the array it would be in JSON. Items are trimmed and empty ones dropped, so a trailing comma is not an entry.

pub fn bool(&self, path: &str, default: bool) -> bool

pub fn environment(&self) -> String

The current environment name: local, production, testing.

pub fn is_local(&self) -> bool

pub fn is_production(&self) -> bool

pub fn debug(&self) -> bool

Whether to show the detailed error page. Never true in production.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

fn clone_from(&mut self, source: &Self)

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.
