Struct Success 

pub struct Success;

Marker diagnostic type representing a successful result.

Its signature is ResultType::Success.

Trait Implementations

impl Clone for Success

fn clone(&self) -> Success

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Success

impl Debug for Success

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

Formats the value using the given formatter.

impl Display for Success

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

Formats the value using the given formatter.

impl Eq for Success

impl Error for Success

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 ErrorDiagnostic for Success

fn signature(&self) -> &'static str

Returns a stable identifier for the specific error classification.

fn tag(&self) -> Option<&Bytes>

Returns an optional tag associated with this error.

fn service(&self) -> Option<&'static str>

Returns the name of the responsible service, if applicable.

fn backtrace(&self) -> Option<&Backtrace>

Returns a backtrace for debugging purposes, if available.

impl Hash for Success

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

where __H: Hasher,

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 for Success

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

Equality operator ==.

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

Inequality operator !=.
