Implementations

impl Operation

pub fn object_type(&self) -> &NamedType

Returns the name of the schema type this operation selects against.

pub fn is_query(&self) -> bool

Returns true if this is a query operation.

pub fn is_mutation(&self) -> bool

Returns true if this is a mutation operation.

pub fn is_subscription(&self) -> bool

Returns true if this is a subscription operation.

pub fn is_introspection(&self, document: &ExecutableDocument) -> bool

Return whether this operation is a query that only selects introspection meta-fields: __type, __schema, and __typename

pub fn root_fields<'doc>( &'doc self, document: &'doc ExecutableDocument, ) -> impl Iterator<Item = &'doc Node<Field>>

Returns an iterator of field selections that are at the root of the response. That is, inline fragments and fragment spreads at the root are traversed, but field sub-selections are not.

See also all_fields.

document is used to look up fragment definitions.

This does not perform field merging nor fragment spreads de-duplication, so multiple items in this iterator may have the same response key, point to the same field definition, or even be the same field selection.

pub fn all_fields<'doc>( &'doc self, document: &'doc ExecutableDocument, ) -> impl Iterator<Item = &'doc Node<Field>>

Returns an iterator of all field selections in this operation.

See also root_fields.

document is used to look up fragment definitions.

This does not perform field merging nor fragment spreads de-duplication, so multiple items in this iterator may have the same response key, point to the same field definition, or even be the same field selection.

pub fn serialize(&self) -> Serialize<'_, Self>

Returns a builder that has chaining methods for setting serialization configuration, and implements the Display and ToString traits by writing GraphQL syntax.

Trait Implementations

impl Clone for Operation

fn clone(&self) -> Operation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Operation

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

Formats the value using the given formatter.

impl Display for Operation

Serialize to GraphQL syntax with the default configuration

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

Formats the value using the given formatter.

impl PartialEq for Operation

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