Trait CredentialStore 

pub trait CredentialStore: Send + Sync {
    // Required methods
    fn get(&self, provider: &str) -> Option<String>;
    fn set(&self, provider: &str, key: &str) -> Result<()>;
    fn delete(&self, provider: &str) -> Result<bool>;
    fn label(&self) -> &'static str;
}

Abstract credential storage so resolution logic tests against an in-memory fake instead of the real OS keyring.

Required Methods

fn get(&self, provider: &str) -> Option<String>

The stored key for provider, if any. Backend failures (no Secret Service, locked keychain) read as None — resolution then simply reports no key, exactly like an unset env var.

fn set(&self, provider: &str, key: &str) -> Result<()>

Store (or replace) provider’s key.

fn delete(&self, provider: &str) -> Result<bool>

Delete provider’s key; Ok(false) when nothing was stored.

fn label(&self) -> &'static str

Human name for confirmations (“Stored key for groq in ”).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
