Function parse_env 

pub fn parse_env(
    path: &str,
    text: &str,
) -> Result<BTreeMap<String, String>, BudgetError>

Parse key=value lines. Blank lines and # comments are skipped; a repeated key is an error, so a snapshot cannot silently lose a value.

Errors

Returns BudgetError::InvalidArtifact for a line without = or a repeated key.
