Config struct represents application config, which is used application-wide.

func Must

func Must(cfg *Config, err error) *Config

Must is a handly wrapper around return results from the NewFromEnv() function, which will panic in case of error. Should be called only in main function, when we don't need to handle errors.

func NewFromEnv

func NewFromEnv() (*Config, error)

NewFromEnv parses the environment variables into the Config struct. Returns an error if any of required variables is missing or contains invalid value.
