Struct AddressResolveError 

pub struct AddressResolveError {
    pub kind: AddressResolveErrorKind,
    pub code: Option<i32>,
    pub message: String,
    pub system_error: Option<Error>,
}

Resolver-specific details stored inside OperationError::Io. Recover this value with io_error.get_ref().and_then(|error| error.downcast_ref::<AddressResolveError>()).

Fields

kind: AddressResolveErrorKind

The portable failure category, which selects the io::ErrorKind when converted into an io::Error.

code: Option<i32>

A backend-specific resolver code (EAI_* or Winsock). Simulators may omit it. Do not interpret it as errno or carry it between platforms.

message: String

A human-readable description, used as this error’s Display output.

system_error: Option<Error>

An underlying system failure, such as errno captured immediately after EAI_SYSTEM.

Trait Implementations

impl Debug for AddressResolveError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for AddressResolveError

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for AddressResolveError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<AddressResolveError> for Error

fn from(error: AddressResolveError) -> Self

Converts to this type from the input type.
