pub struct SelectionSet {
    pub ty: NamedType,
    pub selections: Vec<Selection>,
}

Fields

ty: NamedType

selections: Vec<Selection>

Implementations

impl SelectionSet

pub fn new(ty: NamedType) -> Self

Create a new selection set

pub fn is_empty(&self) -> bool

pub fn push(&mut self, selection: impl Into<Selection>)

pub fn extend( &mut self, selections: impl IntoIterator<Item = impl Into<Selection>>, )

pub fn new_field<'schema>( &self, schema: &'schema Schema, name: Name, ) -> Result<Field, FieldLookupError<'schema>>

Create a new field to be added to this selection set with push

Returns an error if the type of this selection set is not defined or does not have a field named name.

pub fn new_inline_fragment( &self, opt_type_condition: Option<NamedType>, ) -> InlineFragment

Create a new inline fragment to be added to this selection set with push

pub fn new_fragment_spread(&self, fragment_name: Name) -> FragmentSpread

Create a new fragment spread to be added to this selection set with push

pub fn fields(&self) -> impl Iterator<Item = &Node<Field>>

Returns an iterator of field selections directly in this selection set.

Does not recur into inline fragments or fragment spreads.

pub fn serialize(&self) -> Serialize<'_, Self>

Returns a builder that has chaining methods for setting serialization configuration, and implements the Display and ToString traits by writing GraphQL syntax.

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 Display for SelectionSet

Serialize to GraphQL syntax with the default configuration

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 for SelectionSet

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