Expand description

Parser error.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Syntax

Fields

message: String

The message of the error, nicely formatted with newlines.

start: Pos

The start position of the error.

end: Option<Pos>

The end position of the error, if present.

A syntax error occurred.

MultipleRoots

Fields

root: OperationType

The type of root that was duplicated.

schema: Pos

The position of the schema.

pos: Pos

The position of the second root.

The schema contained multiple query, mutation or subscription roots.

MissingQueryRoot

Fields

pos: Pos

The position of the schema.

The schema contained no query root.

MultipleOperations

Fields

anonymous: Pos

The position of the anonymous operation.

operation: Pos

The position of the other operation.

Multiple operations were found in a document with an anonymous one.

OperationDuplicated

Fields

operation: Name

The name of the operation.

first: Pos

The position of the first definition.

second: Pos

The position of the second definition.

An operation is defined multiple times in a document.

FragmentDuplicated

Fields

fragment: Name

The name of the fragment.

first: Pos

The position of the first definition.

second: Pos

The position of the second definition.

A fragment is defined multiple times in a document.

MissingOperation

The document does not contain any operation.

RecursionLimitExceeded

Recursion limit exceeded.

Implementations
