Enum NativeError 

pub enum NativeError {
    Unsupported,
    Denied(String),
    Cancelled,
    Invalid(String),
    Os(String),
}

Why a native call did not do what was asked.

Variants

Unsupported

Not available on this platform, in this build, or in this process (for example notifications from an unbundled macOS binary). Callers treat it as “skip the feature”.

Denied(String)

The OS or the user refused (keychain locked, permission not granted).

Cancelled

The user dismissed a dialog.

Invalid(String)

The caller passed something unusable (an invalid accelerator, a URL with a forbidden scheme).

Os(String)

The OS reported a failure; the text is one line and safe to show.

Implementations

impl NativeError

pub fn is_unsupported(&self) -> bool

Trait Implementations

impl Clone for NativeError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NativeError

impl Eq for NativeError

impl Error for NativeError

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 PartialEq for NativeError

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

Equality operator ==.

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

Inequality operator !=.
