Implementations

impl NetworkError

pub fn connection_failed( addr: impl Into<String>, reason: impl Into<String>, ) -> Self

Create a connection failed error

pub fn connection_timeout(addr: impl Into<String>, timeout_ms: u64) -> Self

Create a connection timeout error

pub fn send_failed(addr: impl Into<String>, reason: impl Into<String>) -> Self

Create a send failed error

pub fn request_timeout(addr: impl Into<String>, timeout_ms: u64) -> Self

pub fn addr(&self) -> &str

Get the associated address if available

Trait Implementations

impl Debug for NetworkError

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

Formats the value using the given formatter.

impl Display for NetworkError

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

Formats the value using the given formatter.

impl Error for NetworkError

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<NetworkError> for RocketMQError

fn from(source: NetworkError) -> Self

Converts to this type from the input type.
