Enum async_graphql::Value

[−] Show declaration

pub enum Value {
    Null,
    Number(Number),
    String(String),

    Enum(Name),
    List(Vec<ConstValue>),
    Object(BTreeMap<Name, ConstValue>),

}

[−] Expand description

A resolved GraphQL value, for example 1 or "Hello World!".

It can be serialized and deserialized. Enums will be converted to strings. Attempting to serialize Upload will fail, and Enum and Upload cannot be deserialized.

Reference.

Variants

Null

Implementations

impl ConstValue[−]

[+] Expand attributes

#[must_use]pub fn into_value(self) -> Value[−]

Convert this ConstValue into a Value.

pub fn into_json(self) -> Result<Value, Error>[−]

Attempt to convert the value into JSON. This is equivalent to the TryFrom implementation.

Errors

Fails if serialization fails (see enum docs for more info).

pub fn from_json(json: Value) -> Result<ConstValue, Error>[−]

Attempt to convert JSON into a value. This is equivalent to the TryFrom implementation.

Errors

Fails if deserialization fails (see enum docs for more info).
