Struct e_utils::dns::LookupError

pub struct LookupError { /* private fields */ }

Available on crate feature dns only.

Struct that stores a lookup error from getaddrinfo or getnameinfo. Can automatically be coerced to an io::Error using ?.

Implementations

impl LookupError

pub fn match_gai_error(err: i32) -> Result<(), Self>

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

Create a new LookupError from a gai error, returned by getaddrinfo and getnameinfo.

pub fn kind(&self) -> LookupErrorKind

Get the error kind explicitly. If this is an io::Error, use From/Into to convert it.

pub fn error_num(&self) -> i32

Get the actual error number. This can be used to find non-standard return codes from some implementations (be careful of portability here).
