Enum ProtocolError 

pub enum ProtocolError {
    ExpectedInitialize(String),
    ExpectedInitialized(String),
    Disconnected,
    AfterShutdown(String),
    InitializeTimeout,
    RequestTimeout,
    Io(Error),
}

Errors that occur during LSP protocol lifecycle management.

These errors represent violations of the LSP protocol’s initialization and shutdown sequences.

Examples

use lsp_server_tokio::ProtocolError;

// Creating protocol errors
let err = ProtocolError::ExpectedInitialize("textDocument/hover".to_string());
assert!(err.to_string().contains("textDocument/hover"));

let err = ProtocolError::Disconnected;
assert!(err.to_string().contains("disconnected"));

Variants

ExpectedInitialize(String)

Expected initialize request, but received a different message.

This occurs when the server is in Uninitialized state and receives a request other than initialize.

ExpectedInitialized(String)

Expected initialized notification, but received a different message.

This occurs when the server is in Initializing state and receives a notification other than initialized.

Disconnected

The connection was disconnected unexpectedly.

This typically occurs when the client closes the connection without sending an exit notification.

AfterShutdown(String)

Received a request after the shutdown request was processed.

After receiving shutdown, only the exit notification is valid.

InitializeTimeout

Timed out waiting for the initialized notification.

RequestTimeout

Timed out waiting for a response to a server-initiated request.

Io(Error)

An I/O error occurred during protocol communication.

Trait Implementations

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Error for ProtocolError

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 ProtocolError

fn from(source: Error) -> Self

Converts to this type from the input type.
