Implementations

impl SessionError

pub fn code(&self) -> i32

Returns the JSON-RPC error code for this error.

pub fn category(&self) -> ErrorCategory

Returns the error category for programmatic handling.

pub fn context(&self) -> Value

Returns structured context about the error for debugging.

pub fn suggestion(&self) -> String

Returns a helpful suggestion for resolving the error.

pub fn is_retryable(&self) -> bool

Returns whether this error is potentially transient and may succeed on retry.

Trait Implementations

impl Debug for SessionError

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

Formats the value using the given formatter.

impl Display for SessionError

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

Formats the value using the given formatter.

impl Error for SessionError

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<PtyError> for SessionError

fn from(source: PtyError) -> Self

Converts to this type from the input type.

impl From<SessionError> for DomainError

fn from(err: SessionError) -> Self

Converts to this type from the input type.
