Struct OperationMap

pub struct OperationMap {
    pub anonymous: Option<Node<Operation>>,
    pub named: IndexMap<Name, Node<Operation>>,
}

Operations definitions for a given executable document

Fields

anonymous: Option<Node<Operation>>

named: IndexMap<Name, Node<Operation>>

Implementations

impl OperationMap

pub fn from_one(operation: impl Into<Node<Operation>>) -> Self

Creates a new OperationMap containing one operation

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn iter(&self) -> impl Iterator<Item = &Node<Operation>>

Returns an iterator of operations, both anonymous and named

pub fn get( &self, name_request: Option<&str>, ) -> Result<&Node<Operation>, RequestError>

Return the relevant operation for a request, or a request error

This is the GetOperation() algorithm in the Executing Requests section of the specification.

A GraphQL request comes with a document (which may contain multiple operations) an an optional operation name. When a name is given the request executes the operation with that name, which is expected to exist. When it is not given / null / None, the document is expected to contain a single operation (which may or may not be named) to avoid ambiguity.

pub fn get_mut( &mut self, name_request: Option<&str>, ) -> Result<&mut Operation, RequestError>

Similar to get but returns a mutable reference.

pub fn insert( &mut self, operation: impl Into<Node<Operation>>, ) -> Option<Node<Operation>>

Insert the given operation in either named_operations or anonymous_operation as appropriate, and return the old operation (if any) with that name (or lack thereof).

Trait Implementations

impl Clone for OperationMap

fn clone(&self) -> OperationMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperationMap

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

Formats the value using the given formatter.

impl Default for OperationMap

fn default() -> OperationMap

Returns the “default value” for a type.

impl PartialEq for OperationMap

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