Implementations

impl Config

pub fn try_from_env() -> Result<Arc<Config>, ConfigError>

Try to load configuration from environment variables

This will:

1. Load .env file if present
2. Parse environment variables
3. Apply convention-based patterns (RPC_URL_{CHAIN_ID})
4. Load chains.toml if specified
5. Validate all configuration

Returns a Result instead of exiting on failure, making it suitable for library usage and programmatic configuration building.

pub fn from_env() -> Arc<Config>

Load configuration from environment variables (fail-fast)

This will:

1. Load .env file if present
2. Parse environment variables
3. Apply convention-based patterns (RPC_URL_{CHAIN_ID})
4. Load chains.toml if specified
5. Validate all configuration

This is a wrapper around try_from_env() that exits the process on failure, suitable for application main binaries.

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

Validate the entire configuration

pub fn builder() -> ConfigBuilder

Create a builder for constructing configuration programmatically
