pub enum InterfacesError {
    Errno(Errno),
    NotSupported(&'static str),
}

InterfacesError is the error type that is returned by all functions in this crate. See the documentation on the individual variants for more information.

Errno(Errno)

Errno indicates that something went wrong with an underlying syscall. The internal value is the errno that was returned.

impl Error for InterfacesError

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

The lower-level source of this error, if any.

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl From<Errno> for InterfacesError

fn from(e: Errno) -> InterfacesError

Converts to this type from the input type.
