Struct apollo_compiler::schema::UnionType

pub struct UnionType {
    pub description: Option<NodeStr>,
    pub name: Name,
    pub directives: DirectiveList,
    pub members: IndexSet<ComponentName>,
}

Fields

description: Option<NodeStr>

name: Name

directives: DirectiveList

members: IndexSet<ComponentName>

• Key: name of a member object type
• Value: which union type extension defined this implementation, or None for the union type definition.

Implementations

impl UnionType

pub fn extensions(&self) -> IndexSet<&ExtensionId>

Collect union type extensions that contribute any component

The order of the returned set is unspecified but deterministic for a given apollo-compiler version.

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 UnionType

fn clone(&self) -> UnionType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnionType

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

Formats the value using the given formatter.

impl Display for UnionType

Serialize to GraphQL syntax with the default configuration

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

Formats the value using the given formatter.

impl From<UnionType> for ExtendedType

fn from(ty: UnionType) -> Self

Converts to this type from the input type.

impl PartialEq for UnionType

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