Function FromConfig

cel/options.go:533–550

FromConfig produces and applies a set of EnvOption values derived from an env.Config object. For configuration elements which refer to features outside of the `cel` package, an optional set of ConfigOptionFactory values may be passed in to support the conversion from static configuration to configu

(config *env.Config, optFactories ...ConfigOptionFactory)

// as the type provider configured at the time when the config is processed is the one used to derive
// type references from the configuration.
func FromConfig(config *env.Config, optFactories ...ConfigOptionFactory) EnvOption {
	return func(e *Env) (*Env, error) {
		if err := config.Validate(); err != nil {
			return nil, err
		}
		opts, err := configToEnvOptions(config, e.CELTypeProvider(), optFactories)
		if err != nil {
			return nil, err
		}
		for _, o := range opts {
			e, err = o(e)
			if err != nil {
				return nil, err
			}
		}
		return e, nil
	}
}

// configToEnvOptions generates a set of EnvOption values (or error) based on a config, a type provider,
// and an optional set of environment options.
