Every method the server exposes. The comment on each records the parameter and result types the schema assigns it; `voption` marks a result the schema permits to be null.

APIFileChanges describes file changes to apply when updating a snapshot. Either InvalidateAll is true (discard all caches) or Changed/Created/Deleted list individual documents.

CheckerNodeParams are parameters for checker methods that operate on a node location.

CheckerSignatureParams are parameters for checker methods that operate on a signature.

CheckerSymbolParams are parameters for checker methods that operate on a symbol.

CheckerTypeParams are parameters for checker methods that operate on a type.

CompilerOptions contains the compiler options exposed by the API.

CompletionEntryLabelDetailsResponse holds additional label display text for a completion entry.

CompletionEntryResponse represents a single completion item.

CompletionInfoResponse wraps a list of completion entries.

DiagnosticResponse is the API response for a single diagnostic.

The schema types this as `string | { uri: string }` - either a path or a document URI - so it is a union here rather than a record with two optional halves. It needs `DocumentIdentifierConverter` to serialise, which `ProtoJson.options` registers; the converter cannot be attached here as an attribute because it is declared against this type and would close the dependency loop.

FormatNodeForInsertionParams are the parameters for the formatNodeForInsertion method.

GetBaseTypeOfLiteralTypeParams returns the base type of a literal type.

GetCompletionsAtPositionParams are the parameters for the getCompletionsAtPosition method.

GetContextualTypeParams returns the contextual type for a node.

GetDiagnosticsParams are parameters for per-file diagnostic methods.

GetIntrinsicTypeParams is used for intrinsic type getters (anyType, stringType, etc.).

GetMemberInModuleExportsParams are parameters for getMemberInModuleExports.

GetParameterTypeParams are the parameters for the getParameterType method.

GetProjectDiagnosticsParams are parameters for project-wide diagnostic methods.

GetPropertyOfTypeParams are parameters for getPropertyOfType (a named property of a type).

GetReferencedSymbolsForNodeParams are the parameters for the getReferencedSymbolsForNode method.

GetReferencesToSymbolInFileParams are the parameters for the getReferencesToSymbolInFile method.

GetSignaturePropertyParams is used for all signature sub-property endpoints.

GetSignatureUsagesParams are the parameters for the getSignatureUsages method.

GetSymbolPropertyParams is used for all symbol sub-property endpoints.

GetSymbolsInScopeParams are parameters for getSymbolsInScope, which returns all symbols visible at a given location.

GetTypeFromTypeNodeParams are the parameters for the getTypeFromTypeNode method.

GetTypeOfSymbolAtLocationParams returns the narrowed type of a symbol at a specific location.

GetTypePropertyParams is used for all type sub-property endpoints.

GetWidenedTypeParams are the parameters for the getWidenedType method.

IndexInfoResponse represents a single index signature.

InitializeResponse is returned by the initialize method.

IsArrayLikeTypeParams checks whether a type is array-like.

IsTypeAssignableToParams checks assignability between two types.

JSDocTagInfo is a single JSDoc tag, mirroring Strada's JSDocTagInfo but with the tag text rendered as a plain string rather than SymbolDisplayPart[].

PrintNodeParams are the parameters for the printNode method.

ProjectFileChanges describes what source files changed within a single project.

Path is a normalized path on disk.

@deprecated Use parsedCommandLine.fileNames.

ReferencedSymbolEntry represents a symbol definition and its references.

ReleaseParams are the parameters for the release method.

Optional: node handle for location context

SignatureToSignatureDeclarationParams are the parameters for the signatureToSignatureDeclaration method.

SignatureUsageResponse represents a single usage of a signature as a name-call pair.

SnapshotChanges describes what changed between the previous latest snapshot and the newly created snapshot. Changes are reported per-project so clients can track cache refs at the (snapshot, project) level.

SourceFileMetadata carries program-stored metadata about a single source file.

SourceFileResponse contains the binary-encoded AST data for a source file. The Data field is base64-encoded binary data in the encoder's format.

Project is the project in which the symbol was first observed. It is the default project for follow-up lookups whose results can vary by project.

TypePredicateResponse is the response for getTypePredicateOfSignature.

Value is literal type data. BigInt literals are encoded as signed decimal strings because JSON cannot represent bigint; absent values are null.

TypeToTypeNodeParams are the parameters for the typeToTypeNode method.

UpdateSnapshotParams are the parameters for creating a new snapshot. All fields are optional. With no fields set, the server adopts the latest LSP state.

UpdateSnapshotResponse is returned by updateSnapshot.

UpdateTemporarySnapshotParams are the parameters for creating a temporary snapshot that overrides a single file's content.

WellKnownSignaturesResponse carries the handle id of the per-checker singleton unknown signature (the signature the checker yields when a call cannot be resolved) so the client can identify it by id without a round-trip on every check.

WellKnownSymbolsResponse carries the handle ids of the per-checker singleton symbols (unknown, undefined, arguments) so the client can identify them by id without a round-trip on every check.
