Struct EnvVarStore 

pub struct EnvVarStore { /* private fields */ }

Environment-variable-backed credential store.

Resolves secrets by name through std::env::var (or an injected reader, for testing). Used as the CI / Docker fallback when the OS keychain is unavailable.

Implementations

impl EnvVarStore

pub fn new() -> Self

Create a new environment variable store with default settings.

Uses DEVBOY_ prefix and enables fallback to unprefixed variables.

pub fn with_prefix(prefix: impl Into<String>) -> Self

Create with a custom prefix.

Example

let store = EnvVarStore::with_prefix("MYAPP");
// Will check MYAPP_GITHUB_TOKEN, then GITHUB_TOKEN

pub fn without_fallback(self) -> Self

Disable fallback to unprefixed environment variables.

When disabled, only {PREFIX}_{KEY} format is checked.
