Function iota_types::parse_iota_fq_name

pub fn parse_iota_fq_name(s: &str) -> Result<(ModuleId, String)>

Parse s as a fully-qualified name: A Module ID (see parse_iota_module_id), followed by ::, and then an identifier (for the module member). Parsing succeeds if and only if s matches this format exactly, with no remaining input. This function is intended for use within the authority codebases.
