Implementations

impl JSONSelection

pub fn apply_to(&self, data: &JSON) -> (Option<JSON>, Vec<ApplyToError>)

pub fn apply_with_vars( &self, data: &JSON, vars: &IndexMap<String, JSON>, ) -> (Option<JSON>, Vec<ApplyToError>)

pub fn shape(&self) -> Shape

impl JSONSelection

pub fn spec(&self) -> ConnectSpec

pub fn named(sub: SubSelection) -> Self

pub fn path(path: PathSelection) -> Self

pub fn empty() -> Self

pub fn is_empty(&self) -> bool

pub fn parse(input: &str) -> Result<Self, JSONSelectionParseError>

pub fn parse_with_spec( input: &str, spec: ConnectSpec, ) -> Result<Self, JSONSelectionParseError>

pub fn variable_references( &self, ) -> impl Iterator<Item = VariableReference<Namespace>> + '_

impl JSONSelection

pub fn apply_selection_set( &self, abstract_types: &IndexSet<String>, document: &ExecutableDocument, selection_set: &SelectionSet, required_keys: Option<&FieldSet>, ) -> Self

Apply a selection set to create a new JSONSelection

Operations from the query planner will never contain key fields (because it already has them from a previous fetch) but we might need those fields for things like sorting entities in a batch. If the optional required_keys is provided, we’ll merge those fields into the selection set before applying it to the JSONSelection.

Trait Implementations

impl Clone for JSONSelection

fn clone(&self) -> JSONSelection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JSONSelection

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

Formats the value using the given formatter.

impl Display for JSONSelection

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

Formats the value using the given formatter.

impl PartialEq for JSONSelection

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