Struct ErrorCode

pub struct ErrorCode(pub i32);

A JSON-RPC error code.

Codes defined and/or used by LSP are defined as associated constants, eg. ErrorCode::REQUEST_FAILED.

See: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#errorCodes

Implementations

impl ErrorCode

pub const PARSE_ERROR: Self

Invalid JSON was received by the server. An error occurred on the server while parsing the JSON text.

Defined by JSON-RPC.

pub const INVALID_REQUEST: Self

The JSON sent is not a valid Request object.

Defined by JSON-RPC.

pub const METHOD_NOT_FOUND: Self

The method does not exist / is not available.

Defined by JSON-RPC.

pub const INVALID_PARAMS: Self

Invalid method parameter(s).

Defined by JSON-RPC.

pub const INTERNAL_ERROR: Self

Internal JSON-RPC error.

Defined by JSON-RPC.

pub const JSONRPC_RESERVED_ERROR_RANGE_START: Self

This is the start range of JSON-RPC reserved error codes. It doesn’t denote a real error code. No LSP error codes should be defined between the start and end range. For backwards compatibility the ServerNotInitialized and the UnknownErrorCode are left in the range.

@since 3.16.0

pub const SERVER_NOT_INITIALIZED: Self

Error code indicating that a server received a notification or request before the server has received the initialize request.

pub const UNKNOWN_ERROR_CODE: Self

(Defined by LSP specification without description)

pub const JSONRPC_RESERVED_ERROR_RANGE_END: Self

This is the end range of JSON-RPC reserved error codes. It doesn’t denote a real error code.

@since 3.16.0

pub const LSP_RESERVED_ERROR_RANGE_START: Self

This is the start range of LSP reserved error codes. It doesn’t denote a real error code.

@since 3.16.0

pub const REQUEST_FAILED: Self

A request failed but it was syntactically correct, e.g the method name was known and the parameters were valid. The error message should contain human readable information about why the request failed.

@since 3.17.0

pub const SERVER_CANCELLED: Self

The server cancelled the request. This error code should only be used for requests that explicitly support being server cancellable.

@since 3.17.0

pub const CONTENT_MODIFIED: Self

The server detected that the content of a document got modified outside normal conditions. A server should NOT send this error code if it detects a content change in it unprocessed messages. The result even computed on an older state might still be useful for the client.

If a client decides that a result is not of any use anymore the client should cancel the request.

pub const REQUEST_CANCELLED: Self

The client has canceled a request and a server as detected the cancel.

pub const LSP_RESERVED_ERROR_RANGE_END: Self

This is the end range of LSP reserved error codes. It doesn’t denote a real error code.

@since 3.16.0

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErrorCode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Error for ErrorCode

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<i32> for ErrorCode

fn from(i: i32) -> Self

Converts to this type from the input type.

impl Hash for ErrorCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ErrorCode

fn cmp(&self, other: &ErrorCode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ErrorCode

fn eq(&self, other: &ErrorCode) -> 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.

fn partial_cmp(&self, other: &ErrorCode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for ErrorCode

impl Eq for ErrorCode
