Enum Value

pub enum Value<'a> {
    Variable(Variable<'a>),
    String(StringValue<'a>),
    Float(FloatValue<'a>),
    Int(IntValue<'a>),
    Boolean(BooleanValue),
    Enum(EnumValue<'a>),
    List(ListValue<'a>),
    Object(ObjectValue<'a>),
    Null,
}

AST Node of possible input values in GraphQL.

Fields and Directives accept input values as arguments.

Implementations

impl<'a> Value<'a>

pub fn is_truthy(&self, variables: Option<&Variables<'a>>) -> bool

Trait Implementations

impl<'a> Clone for Value<'a>

fn clone(&self) -> Value<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Value<'a>

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

Formats the value using the given formatter.

impl<'a> From<BooleanValue> for Value<'a>

fn from(x: BooleanValue) -> Self

Converts to this type from the input type.

impl<'a> From<EnumValue<'a>> for Value<'a>

fn from(x: EnumValue<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<FloatValue<'a>> for Value<'a>

fn from(x: FloatValue<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<IntValue<'a>> for Value<'a>

fn from(x: IntValue<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<ListValue<'a>> for Value<'a>

fn from(x: ListValue<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<ObjectValue<'a>> for Value<'a>

fn from(x: ObjectValue<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<StringValue<'a>> for Value<'a>

fn from(x: StringValue<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<Variable<'a>> for Value<'a>

fn from(x: Variable<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for Value<'a>

fn eq(&self, other: &Value<'a>) -> 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.

impl<'a> PrintNode for Value<'a>

fn write_to_buffer(&self, level: usize, buffer: &mut dyn Write) -> Result

Write an AST node to a buffer implementing the Write trait.

fn print(&self) -> String

Print an AST Node to source text as a String allocated on the heap.

impl<'a> ValueFromNode<'a> for Value<'a>

fn to_json(self, variables: Option<&Variables<'a>>) -> JSValue

Convert current AST Value Node to a serde_json::Value with given Variables.
