Fields

code: i32

Application-defined JSON-RPC error code.

message: String

Human-readable error message.

data: Option<Value>

Optional structured error data.

Implementations

impl LspError

pub fn internal(e: impl Display) -> Self

Construct an internal-error response from a displayable value.

pub fn invalid_params(e: impl Display) -> Self

Construct an invalid-params response from a displayable value.

pub fn invalid_request(e: impl Display) -> Self

Construct an invalid-request response from a displayable value.

pub fn code(&self) -> i32

The JSON-RPC/LSP numeric error code.

pub fn message(&self) -> String

The human-readable error message.

pub fn data(&self) -> Option<&Value>

Optional structured error data for an application-defined server error.

Trait Implementations

impl Debug for LspError

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

Formats the value using the given formatter.

impl Display for LspError

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

Formats the value using the given formatter.

impl Error for LspError

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<LspError> for Error

fn from(source: LspError) -> Self

Converts to this type from the input type.
