Struct apollo_compiler::database::hir::Field

pub struct Field { /* private fields */ }

Implementations

impl Field

pub fn alias(&self) -> Option<&Alias>

Get a reference to the field’s alias.

pub fn name(&self) -> &str

Get the field’s name, corresponding to the definition it looks up.

For example, in this operation, the .name() is “sourceField”:

query GetField { alias: sourceField }

pub fn response_name(&self) -> &str

Get the name that will be used for this field selection in response formatting.

For example, in this operation, the .response_name() is “sourceField”:

query GetField { sourceField }

But in this operation that uses an alias, the .response_name() is “responseField”:

query GetField { responseField: sourceField }

pub fn ty(&self, db: &dyn HirDatabase) -> Option<Type>

Get a reference to field’s type.

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

Get the field’s parent type definition.

pub fn field_definition(&self, db: &dyn HirDatabase) -> Option<FieldDefinition>

Get field’s original field definition.

pub fn arguments(&self) -> &[Argument]

Get a reference to the field’s arguments.

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

Get a reference to the field’s 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 selection_set(&self) -> &SelectionSet

Get a reference to the field’s selection set.

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

Get variables used in the field, including in sub-selections.

For example, with this field:

{
  field(arg: $arg) {
    number(formatAs: $format)
  }
}

the used variables are $arg and $format.

pub fn loc(&self) -> HirNodeLocation

Get the AST location information for this HIR node.

pub fn is_introspection(&self) -> bool

Returns true if this is an introspection field (i.e. it’s Self::name() is one of __type, or __schema).

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.

impl Hash for Field

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<Field> for Field

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