pub fn parse_dotenv(input: &str, opts: Options) -> Result<Config, AdapterError>Expand description
Read .env file content.
The dialect is deliberately small (spec F1.7): NAME=value, an optional
export prefix, whole-line # comments, single quotes taken literally,
double quotes with \n \r \t \\ \". Multi-line values and trailing
comments are unsupported — an unquoted value containing # is an error
rather than a guess. No ${...} expansion.
