Struct Error 

pub struct Error { /* private fields */ }

Errors returned by the SDK.

Implementations

impl Error

pub fn kind(&self) -> &ErrorKind

The ErrorKind of this Error.

pub fn message(&self) -> Option<&str>

The message provided when this Error was constructed, or None.

pub fn with_message<C>(kind: ErrorKind, message: C) -> Self

where C: Into<Cow<'static, str>>,

Create an Error with a message.

pub fn is_transport_failure(&self) -> bool

Returns true if this error indicates the transport is broken — the CLI process exited, the connection was lost, or an I/O failure occurred. Callers should discard the client and create a fresh one.

pub fn rpc_code(&self) -> Option<i32>

Returns the JSON-RPC error code if this is an ErrorKind::Rpc 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, f: &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
