Struct apollo_compiler::database::hir::FragmentSpread

pub struct FragmentSpread { /* private fields */ }

Implementations

impl FragmentSpread

pub fn name(&self) -> &str

Get a reference to the fragment spread’s name.

pub fn fragment(&self, db: &dyn HirDatabase) -> Option<Arc<FragmentDefinition>>

Get the fragment definition this fragment spread is referencing.

pub fn parent_type(&self, db: &dyn HirDatabase) -> Option<TypeDefinition>

Get the type this fragment is spread onto.

Examples

type Query {
    field: X
}
query {
    ...fragment
    field { ...subFragment }
}

fragment.parent_type() is Query. subFragment.parent_type() is X.

pub fn self_used_variables(&self) -> impl Iterator<Item = Variable> + '_

Return an iterator over the variables used in directives on this spread.

Variables used by the fragment definition are not included. For that, use variables().

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

Get fragment spread’s defined variables.

pub fn directives(&self) -> &[Directive]

Get a reference to fragment spread directives.

pub fn directive_by_name(&self, name: &str) -> Option<&Directive>

Returns the first directive with the given name.

For repeatable directives, see directives_by_name (plural).

pub fn directives_by_name<'def: 'name, 'name>( &'def self, name: &'name str ) -> impl Iterator<Item = &'def Directive> + 'name

Returns an iterator of directives with the given name.

For non-repeatable directives, directive_by_name (singular).

pub fn loc(&self) -> HirNodeLocation

Get the AST location information for this HIR node.

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

Returns true if the fragment referenced by this spread exists and its SelectionSet is an introspection.

Trait Implementations

impl Clone for FragmentSpread

fn clone(&self) -> FragmentSpread

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FragmentSpread

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

Formats the value using the given formatter.

impl Hash for FragmentSpread

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<FragmentSpread> for FragmentSpread

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