[−][src]Struct dns_lookup::LookupError
Struct that stores a lookup error from getaddrinfo
or getnameinfo. Can automatically be coerced to an io::Error using ?.
Methods
impl LookupError[src]
pub fn match_gai_error(err: i32) -> Result<(), Self>[src]
Match a gai error, returning Ok() if it's
0. Otherwise return Err(LookupError) with
the specific error details.
pub fn new(err: i32) -> Self[src]
Create a new LookupError from a gai error,
returned by getaddrinfo and getnameinfo.
pub fn kind(&self) -> LookupErrorKind[src]
Get the error kind explicitly. If this is an io::Error, use From/Into to convert it.
pub fn error_num(&self) -> i32[src]
Get the actual error number. This can be used to find non-standard return codes from some implementations (be careful of portability here).
