Struct Operation

pub struct Operation {
    pub operation_type: OperationType,
    pub name: Option<Name>,
    pub variables: Vec<Node<VariableDefinition>>,
    pub directives: DirectiveList,
    pub selection_set: SelectionSet,
}

An OperationDefinition annotated with type information.

Fields

operation_type: OperationType

name: Option<Name>

variables: Vec<Node<VariableDefinition>>

directives: DirectiveList

selection_set: SelectionSet

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, so multiple items in this iterator may have the same response key or point to the same field definition. Named fragments however are only traversed once even if spread multiple times.

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, so multiple items in this iterator may have the same response key or point to the same field definition. Named fragments however are only traversed once even if spread multiple times.

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 duplicate of the value.

const 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.
