Struct Error 

pub struct Error {
    pub code: ErrorCode,
    pub message: Cow<'static, str>,
    pub data: Option<Value>,
}

A JSON-RPC error object.

Fields

code: ErrorCode

A number indicating the error type that occurred.

message: Cow<'static, str>

A short description of the error.

data: Option<Value>

Additional information about the error, if any.

Implementations

impl Error

pub const fn new(code: ErrorCode) -> Self

Creates a new error from the given ErrorCode.

pub const fn parse_error() -> Self

Creates a new parse error (-32700).

pub const fn invalid_request() -> Self

Creates a new “invalid request” error (-32600).

pub const fn method_not_found() -> Self

Creates a new “method not found” error (-32601).

pub fn invalid_params<M>(message: M) -> Self

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

Creates a new “invalid params” error (-32602).

pub const fn internal_error() -> Self

Creates a new internal error (-32603).

pub const fn server_not_initialized() -> Self

Creates a new “server not initialized” error (-32002).

Compatibility

This error code is defined by the Language Server Protocol.

pub const fn request_cancelled() -> Self

Creates a new “request cancelled” error (-32800).

Compatibility

This error code is defined by the Language Server Protocol.

pub const fn content_modified() -> Self

Creates a new “content modified” error (-32801).

Compatibility

This error code is defined by the Language Server Protocol.

pub const fn server_cancelled() -> Self

Creates a new “server cancelled” error (-32802).

Compatibility

This error code is defined by the Language Server Protocol.

pub fn request_failed<M>(message: M) -> Self

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

Creates a new “request failed” server error (-32803).

Used to propagate runtime dispatch failures from the autonomic mesh.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Error

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

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 IntoLsp for Error

type Target = ResponseError

The target lsp_types_max type.

fn into_lsp(self) -> Self::Target

Converts this type into the target lsp_types_max type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Error

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
