Enum FetchDataPathElement 

pub enum FetchDataPathElement {
    Key(Name, Option<Conditions>),
    AnyIndex(Option<Conditions>),
    TypenameEquals(Name),
    Parent,
}

Vectors of this element match path(s) to a value in fetch data. Each element is (1) a key in object data, (2) any index in array data (often serialized as @), (3) a typename constraint on the object data at that point in the path(s) (a path should only match for objects whose __typename is the provided type), or (4) a parent indicator to move upwards one level in the object.

It’s possible for vectors of this element to match no paths in fetch data, e.g. if an object key doesn’t exist, or if an object’s __typename doesn’t equal the provided one. If this occurs, then query plan execution should not execute the instruction this path is associated with.

The path starts at the top of the data it is applied to. So for instance, for fetch data inputs, the path starts at the root of the object representing those inputs.

Note that the @ is currently optional in some contexts, as query plan execution may assume upon encountering array data in a path that it should match the remaining path to the array’s elements.

Trait Implementations

impl Clone for FetchDataPathElement

fn clone(&self) -> FetchDataPathElement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FetchDataPathElement

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FetchDataPathElement

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FetchDataPathElement

PORT_NOTE: Corresponds to GroupPath.updatedResponsePath in buildPlan.ts

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

Formats the value using the given formatter.

impl Hash for FetchDataPathElement

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FetchDataPathElement

fn eq(&self, other: &FetchDataPathElement) -> 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 Serialize for FetchDataPathElement

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
