Enum NoError

pub enum NoError {}

A special error type for a method that doesn’t have any defined error return. You can’t actually encounter a value of this type in real life; it’s here to satisfy type requirements.

Trait Implementations

impl Clone for NoError

fn clone(&self) -> NoError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NoError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NoError

fn deserialize<D: Deserializer<'de>>(_: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for NoError

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

Formats the value using the given formatter.

impl Error for NoError

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 NoError

fn eq(&self, _: &NoError) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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