Implementations

impl ClientConfig

pub fn load(args: ClientArgs) -> Result<Self, ConfigError>

Load configuration from multiple sources in order of precedence:

1. Command line arguments (highest priority)
2. Environment variables (handled by clap’s env attribute on ClientArgs)
3. Configuration file
4. Default values (lowest priority)

Adding New Arguments

When you add a new field to ClientArgs:

1. Add the corresponding override logic below in the “Apply CLI argument overrides” section
2. Map the ClientArgs field to the appropriate ClientConfig field
3. Add a test in the tests module to verify the override works

pub fn validate(&self) -> Result<(), ConfigError>

Validate the configuration

pub fn grpc_endpoint(&self) -> &str

Get the gRPC endpoint for backward compatibility

pub fn timeout_secs(&self) -> Option<u64>

Get the timeout in seconds for backward compatibility

pub fn for_testing(endpoint: impl Into<String>) -> Self

Create a simple client config for testing

pub fn with_cache_path(self, cache_path: Option<PathBuf>) -> Self

Apply cache path override if provided

pub fn with_timeout(self, timeout_secs: u64) -> Self

Set timeout for the connection

pub fn with_endpoint(self, endpoint: String) -> Self

Set the server endpoint for both connection and cache
