Implementations

impl Value

pub fn is_null(&self) -> bool

pub fn as_enum(&self) -> Option<&Name>

pub fn as_variable(&self) -> Option<&Name>

pub fn as_str(&self) -> Option<&str>

pub fn to_f64(&self) -> Option<f64>

Convert a FloatValue or IntValue to floating point representation.

Returns None if the value is of a different kind, or if the conversion overflows.

pub fn to_i32(&self) -> Option<i32>

pub fn to_bool(&self) -> Option<bool>

pub fn as_list(&self) -> Option<&[Node<Value>]>

pub fn as_object(&self) -> Option<&[(Name, Node<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 Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Value

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Value

Serialize to GraphQL syntax with the default configuration

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

Formats the value using the given formatter.

impl From<&String> for Value

fn from(value: &String) -> Self

Converts to this type from the input type.

impl From<&str> for Value

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<()> for Value

The Rust unit value a.k.a empty tuple converts to Value::Null.

fn from(_value: ()) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(value: i32) -> Self

Converts to this type from the input type.

impl Hash for Value

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 Value

fn eq(&self, other: &Value) -> 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 Serialize for Value

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Value

impl StructuralPartialEq for Value
