Implementations

impl Value

pub fn is_same_value(&self, other: &Value) -> bool

Returns true if other represents the same value as self. This is different from the Eq implementation as it ignores location information.

pub fn loc(&self) -> HirNodeLocation

Get current value’s location.

pub fn variables(&self) -> Vec<Variable>

pub fn kind(&self) -> &str

pub fn is_variable(&self) -> bool

Returns true if the value is Variable.

pub fn is_null(&self) -> bool

Returns true if the value is Null.

pub fn as_i32(&self) -> Option<i32>

Returns an i32 if the value is a number and can be represented as an i32.

pub fn as_f64(&self) -> Option<f64>

Returns an f64 if the value is a number and can be represented as an f64.

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

Returns a str if the value is a string.

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

Returns true/false if the value is a boolean.

pub fn as_list(&self) -> Option<&Vec<Value>>

Returns the inner list if the value is a List type.

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

Returns a keys/values list if the value is an input object.

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

Returns the hir::Variable if the value is a variable reference.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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 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<Value> for Value

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

impl TryFrom<&Value> for f64

Coerce to a Float input type (from either Float or Int syntax)

https://spec.graphql.org/draft/#sec-Float.Input-Coercion

type Error = FloatCoercionError

The type returned in the event of a conversion error.

fn try_from(value: &Value) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&Value> for i32

Coerce to an Int input type

https://spec.graphql.org/draft/#sec-Int.Input-Coercion

type Error = IntCoercionError

The type returned in the event of a conversion error.

fn try_from(value: &Value) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for f64

Coerce to a Float input type (from either Float or Int syntax)

https://spec.graphql.org/draft/#sec-Float.Input-Coercion

type Error = FloatCoercionError

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for i32

Coerce to an Int input type

https://spec.graphql.org/draft/#sec-Int.Input-Coercion

type Error = IntCoercionError

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>

Performs the conversion.
