Enum ResolveError 

pub enum ResolveError {
    Private {
        addr: IpAddr,
    },
    Blocked {
        addr: Option<IpAddr>,
        class: Option<AddressClass>,
        reason: String,
    },
    Dns(HttpError),
}

Why [AddressPolicy::resolve_vetted_async] refused a host.

Variants

Private

A private address (RFC 1918, CGNAT or unique-local) that the policy would admit once the caller approves it, for example through AddressPolicy::allow_private_resolution.

Fields

addr: IpAddr

Blocked

Refused outright: link-local or metadata, a denied range, a custom denial, or a name rule.

Fields

addr: Option<IpAddr>

class: Option<AddressClass>

reason: String

Dns(HttpError)

The name did not resolve, or the lookup failed.

Trait Implementations

impl Debug for ResolveError

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

Formats the value using the given formatter.

impl Display for ResolveError

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

Formats the value using the given formatter.

impl Error for ResolveError

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.
