Enum Error 

pub enum Error {
    Io(Error),
    Json(Error),
    Provider(ErrorCode),
    UnexpectedResponseId {
        expected: u64,
        got: u64,
    },
    UnexpectedResponseMethod,
    ProcessExited,
}

Error types for protocol operations.

Variants

Io(Error)

An I/O error occurred on the underlying stream.

Json(Error)

JSON serialization or deserialization failed.

Provider(ErrorCode)

The provider returned an error response.

UnexpectedResponseId

The response ID did not match the request ID.

Fields

expected: u64

got: u64

UnexpectedResponseMethod

The response method did not match what was expected.

ProcessExited

The provider process exited (stdin/stdout reached EOF).

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ErrorCode> for Error

fn from(source: ErrorCode) -> Self

Converts to this type from the input type.

impl From<ErrorPayload> for Error

fn from(p: ErrorPayload) -> Self

Converts to this type from the input type.
