Parser error.

Variants (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

A syntax error occurred.

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.

MultipleRoots

The schema contained multiple query, mutation or subscription roots.

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.

MissingQueryRoot

The schema contained no query root.

Fields

pos: Pos

The position of the schema.

MultipleOperations

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

Fields

anonymous: Pos

The position of the anonymous operation.

operation: Pos

The position of the other operation.

OperationDuplicated

An operation is defined multiple times in a document.

Fields

operation: Name

The name of the operation.

first: Pos

The position of the first definition.

second: Pos

The position of the second definition.

FragmentDuplicated

A fragment is defined multiple times in a document.

Fields

fragment: Name

The name of the fragment.

first: Pos

The position of the first definition.

second: Pos

The position of the second definition.

MissingOperation

The document does not contain any operation.

RecursionLimitExceeded

Recursion limit exceeded.

Implementations

impl Error

pub fn positions(&self) -> ErrorPositions

Get an iterator over the positions of the error.

The iterator is ordered from most important to least important position.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<R: RuleType> From<Error<R>> for Error

fn from(err: Error<R>) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

impl Eq for Error
