Enum Error 

pub enum Error {
    Backend(String),
    Unsupported(&'static str),
    MissingCapability(&'static str),
    Parse(String),
    NotFound(String),
    Io(Error),
}

Crate-wide error type. Backends wrap their own errors in Error::Backend.

Variants

Backend(String)

An error from a backend (netlink, D-Bus, shell-out, etc.).

Unsupported(&'static str)

The requested operation is not supported on this platform or by the current backend.

MissingCapability(&'static str)

The operation requires a capability (e.g. CAP_NET_RAW) that is absent.

Parse(String)

A parsing failure (e.g. malformed JSON from nft, unexpected kernel attribute layout).

NotFound(String)

A requested resource (interface, route, DNS answer, etc.) was not found.

Io(Error)

Wrapped std::io::Error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
