directives: DirectiveList

Implementations

impl InputValueDefinition

pub fn is_required(&self) -> bool

Returns true if usage sites are required to provide a value for this input value.

An input value is required when:

• its type is non-null, and
• it does not have a default value

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 InputValueDefinition

fn clone(&self) -> InputValueDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InputValueDefinition

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

Formats the value using the given formatter.

impl Display for InputValueDefinition

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 InputValueDefinition

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 InputValueDefinition

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