Implementations

impl VoltError

pub fn is_connection_fatal(&self) -> bool

Returns true if this error indicates a fatal connection problem that requires the connection to be replaced/healed.

pub fn message_too_large(size: usize) -> Self

pub fn connection_closed() -> Self

pub fn timeout() -> Self

Trait Implementations

impl Debug for VoltError

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

Formats the value using the given formatter.

impl Display for VoltError

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

Formats the value using the given formatter.

impl Error for VoltError

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.
