//! In this module we only define constants for lsp specific error codes.

/// Defined in the LSP specification but in the range reserved for JSON-RPC error codes,
/// namely the -32099 to -32000 "Reserved for implementation-defined server-errors." range.
/// The code has, nonetheless, been left in this range for backwards compatibility reasons.
