Struct AppError

pub struct AppError { /* private fields */ }

App specific error.

Implementations

impl AppError

pub fn new(error_code: VarInt, reason: impl Into<Cow<'static, str>>) -> AppError

Create a new app error with the given app error code and reason.

pub fn error_code(&self) -> u64

Return the error code.

The error code is an application error code.

pub fn reason(&self) -> &str

Return the reason of this error.

Trait Implementations

impl Clone for AppError

fn clone(&self) -> AppError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppError

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

Formats the value using the given formatter.

impl Display for AppError

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

Formats the value using the given formatter.

impl Error for AppError

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 From<AppError> for ConnectionCloseFrame

fn from(e: AppError) -> ConnectionCloseFrame

Converts to this type from the input type.

impl From<AppError> for Error

fn from(value: AppError) -> Error

Converts to this type from the input type.

impl PartialEq for AppError

fn eq(&self, other: &AppError) -> 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.
