Implementations

impl RouterError

pub fn backend_with_epoch( channel: u16, epoch: u32, corr: u64, message: impl Into<String>, ) -> Self

pub fn route_error( channel: u16, corr: u64, code: impl Into<String>, message: impl Into<String>, ) -> Self

pub fn route_error_with_epoch( channel: u16, epoch: u32, corr: u64, code: impl Into<String>, message: impl Into<String>, ) -> Self

pub fn to_error_frame(&self) -> Option<Frame>

Trait Implementations

impl Clone for RouterError

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 RouterError

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

Formats the value using the given formatter.

impl Display for RouterError

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

Formats the value using the given formatter.

impl Eq for RouterError

impl Error for RouterError

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 RouterError

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

Equality operator ==.

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

Inequality operator !=.
