Enum endpoint_sec_sys::ReturnError

pub enum ReturnError {
    Error,
    Unknown(es_return_t),
    ApiUnavailable,
}

Available on macOS only.

Basic error without additional informations.

Usually constructed using es_return_t::ok().

Variants

Error

See ES_RETURN_ERROR

Unknown(es_return_t)

Catches new variants in the C enum

ApiUnavailable

Used to signal a call to an unavailable API, either because it was removed or because it is only available in higher versions (eg 12.0+ when running on macOS 11.0)

Trait Implementations

impl Clone for ReturnError

fn clone(&self) -> ReturnError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReturnError

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

Formats the value using the given formatter.

impl Display for ReturnError

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

Formats the value using the given formatter.

impl Error for ReturnError

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

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, 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 Hash for ReturnError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<ReturnError> for ReturnError

fn eq(&self, other: &ReturnError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
