Struct SettingsEnv 

pub struct SettingsEnv { /* private fields */ }

An EnvSource with the settings/profile fallback — the value form of get_env_var.

Reads the real process environment first, then the active profile’s env (or the base env when no profile is active) in $HOME/.omni-dev/settings.json.

Pass &SettingsEnv::load() from a thin production wrapper; tests inject a pure MapEnv into the same *_with(&impl EnvSource, …) seam instead of mutating the process environment.

Implementations

impl SettingsEnv

pub fn load() -> Self

Loads settings from the default location, falling back to an empty settings map if they are absent or unreadable (env-only behaviour). The active profile is read from OMNI_DEV_PROFILE.

pub fn load_with_profile(profile: Option<&str>) -> Self

Like load but with the active profile supplied explicitly — for tests and embedders that select a profile without setting OMNI_DEV_PROFILE in the process environment.

Trait Implementations

impl Debug for SettingsEnv

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SettingsEnv

fn default() -> SettingsEnv

Returns the “default value” for a type.

impl EnvSource for SettingsEnv

fn var(&self, key: &str) -> Option<String>

Returns the value of key, or None if it is unset (or, for the process environment, not valid Unicode).

fn var_any(&self, keys: &[&str]) -> Option<String>

Returns the first set value among keys, in order.
