Function mail_internals::bind::idna::puny_code_domain

pub fn puny_code_domain<R: AsRef<str>>(
    domain: R
) -> Result<SoftAsciiString, EncodingError>

uses puny code on given domain to return a ascii representation

Implementation Detail

this function uses idna::domain_to_ascii, see the idna crates documentation fore more details on how exactly all edgecase are handled

Note

that this function does not validate the domain, e.g. if you puny code the domain "this seems\0so;wrong" it will return Ok("this seems\0so;wrong")
