Struct juniper::Object

pub struct Object { /* fields omitted */ }

A Object value

Methods

impl Object

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) -> Option<Value> where     K: Into<String>,     &'a str: PartialEq<K>,

Add a new field with a value

If there is already a field with the same name the old value is returned

pub fn contains_field<K>(&self, f: K) -> bool where     &'a str: PartialEq<K>,

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

pub fn iter(&self) -> FieldIter

Get a iterator over all field value pairs

This method returns a iterator over &'a (String, Value)

pub fn iter_mut(&mut self) -> FieldIterMut

Get a iterator over all mutable field value pairs

This method returns a iterator over &mut 'a (String, Value)

pub fn field_count(&self) -> usize

Get the current number of fields

pub fn get_field_value<K>(&self, key: K) -> Option<&Value> where     &'a str: PartialEq<K>,

Get the value for a given field

Trait Implementations

impl Debug for Object

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

Formats the value using the given formatter.

impl PartialEq for Object

fn eq(&self, other: &Object) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Object) -> bool

This method tests for !=.

impl Clone for Object

fn clone(&self) -> Object

Returns a copy of the value.

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

Performs copy-assignment from source.

impl IntoIterator for Object

type Item = (String, Value)

The type of the elements being iterated over.

type IntoIter = IntoIter<Self::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl From<Object> for Value

fn from(o: Object) -> Self

Performs the conversion.

impl<K> FromIterator<(K, Value)> for Object where     K: Into<String>,     &'a str: PartialEq<K>,

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

Creates a value from an iterator.

impl Serialize for Object

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

Serialize this value into the given Serde serializer.
