Trait for pluggable credential sources.

Each implementation represents one way to obtain API credentials (e.g. environment variables, saved OAuth tokens, external tool discovery).

Required Methods

fn id(&self) -> &str

Unique identifier for this resolver (e.g. "env", "codineer-oauth", "claude-code").

fn display_name(&self) -> &str

Human-readable name shown in UI (e.g. "Environment Variables").

fn priority(&self) -> u16

Lower priority values are tried first. Convention:

• 100: environment variables
• 200: Codineer OAuth
• 300: external tool discovery (Claude Code, etc.)

fn resolve(&self) -> Result<Option<ResolvedCredential>, CredentialError>

Attempt to resolve credentials. Returns Ok(None) if this source has no credentials (and the chain should try the next resolver).

Provided Methods

fn supports_login(&self) -> bool

Whether this resolver supports interactive login().

fn login(&self) -> Result<(), Box<dyn Error>>

Run an interactive login flow. Only called when supports_login() is true.

fn logout(&self) -> Result<(), Box<dyn Error>>

Clear saved credentials. Only called when supports_login() is true.
