Implementations

impl Error

pub fn transaction_not_found( key: TransactionKey, context: impl Into<String>, ) -> Self

Create a new TransactionNotFound error with context

pub fn transport_error(source: Error, context: impl Into<String>) -> Self

Create a new TransportError with context

pub fn invalid_state_transition( transaction_kind: TransactionKind, from_state: TransactionState, to_state: TransactionState, transaction_id: Option<TransactionKey>, ) -> Self

Create a new InvalidStateTransition error

pub fn channel_error(context: impl Into<String>) -> Self

Create a new ChannelError with context

pub fn transaction_timeout( key: TransactionKey, timer: impl Into<String>, ) -> Self

Create a new TransactionTimeout error

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<&str> for Error

fn from(s: &str) -> Self

impl From<Error> for Error

fn from(source: Error) -> Self

impl<T> From<SendError<T>> for Error

fn from(e: SendError<T>) -> Self

Converts to this type from the input type.

impl From<String> for Error

fn from(s: String) -> Self

Converts to this type from the input type.
