Struct apollo_compiler::database::hir::SelectionSet

pub struct SelectionSet { /* private fields */ }

Implementations

impl SelectionSet

pub fn selection(&self) -> &[Selection]

Get a reference to the selection set’s selection.

pub fn fields(&self) -> Vec<Field>

Get a refernce to the selection set’s fields (not inline fragments, or fragment spreads).

pub fn fragment_spreads(&self) -> Vec<FragmentSpread>

Get a reference to selection set’s fragment spread.

pub fn inline_fragments(&self) -> Vec<InlineFragment>

Get a reference to selection set’s inline fragments.

pub fn field(&self, name: &str) -> Option<&Field>

Find a field a selection set.

pub fn variables(&self, db: &dyn HirDatabase) -> Vec<Variable>

Get all variables used in this selection set.

pub fn is_introspection(&self, db: &dyn HirDatabase) -> bool

Returns true if all the Selections in this selection set are themselves introspections.

pub fn concat(&self, other: &SelectionSet) -> SelectionSet

Create a selection set for the concatenation of two selection sets’ fields.

This does not deduplicate fields: if the two selection sets both select a field a, the merged set will select field a twice.

Trait Implementations

impl Clone for SelectionSet

fn clone(&self) -> SelectionSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionSet

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

Formats the value using the given formatter.

impl Hash for SelectionSet

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<SelectionSet> for SelectionSet

fn eq(&self, other: &SelectionSet) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
