Struct juniper::Object

pub struct Object<S> { /* private fields */ }

A Object value

Implementations

impl<S> Object<S>

pub fn with_capacity(size: usize) -> Self

Create a new Object value with a fixed number of preallocated slots for field-value pairs

pub fn add_field<K>(&mut self, k: K, value: Value<S>) -> Option<Value<S>>where
    K: AsRef<str> + Into<String>,

Add a new field with a value

If there is already a field for the given key any both values are objects, they are merged.

Otherwise the existing value is replaced and returned.

pub fn contains_field<K: AsRef<str>>(&self, k: K) -> bool

Check if the object already contains a field with the given name

pub fn iter(&self) -> impl Iterator<Item = (&String, &Value<S>)>

Get a iterator over all field value pairs

pub fn iter_mut(&mut self) -> impl Iterator<Item = (&String, &mut Value<S>)>

Get a iterator over all mutable field value pairs

pub fn field_count(&self) -> usize

Get the current number of fields

pub fn get_field_value<K: AsRef<str>>(&self, key: K) -> Option<&Value<S>>

Get the value for a given field

pub fn get_mut_field_value<K: AsRef<str>>(
    &mut self,
    key: K
) -> Option<&mut Value<S>>

Get the mutable value for a given field

Trait Implementations

impl<S: Clone> Clone for Object<S>

fn clone(&self) -> Object<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for Object<S>

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

Formats the value using the given formatter.

impl<S> From<Object<S>> for Value<S>

fn from(o: Object<S>) -> Self

Converts to this type from the input type.

impl<K, S> FromIterator<(K, Value<S>)> for Object<S>where
    K: AsRef<str> + Into<String>,

fn from_iter<I>(iter: I) -> Selfwhere
    I: IntoIterator<Item = (K, Value<S>)>,

Creates a value from an iterator.

impl<S> IntoIterator for Object<S>

type Item = (String, Value<S>)

The type of the elements being iterated over.

type IntoIter = IntoIter<String, Value<S>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<S: PartialEq> PartialEq<Object<S>> for Object<S>

fn eq(&self, other: &Object<S>) -> 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<T> Serialize for Object<T>where
    T: Serialize,

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.
