Struct nyoom_json::ObjectWriter

pub struct ObjectWriter<S: JsonBuffer> { /* private fields */ }

A serializer for a JSON object.

Implementations

impl<S: JsonBuffer> ObjectWriter<S>

pub fn field<K: Key>(&mut self, key: K, val: impl WriteToJson<S>)

Adds a field to this object.

Examples

let mut obj = ser.object();
obj.field("kind", "cat");
obj.field("has_been_fed", false);
obj.field("meow_decibels", 45);
obj.end();

pub fn complex_field<K, F>(&mut self, key: K, encode: F)where K: Key, F: FnOnce(SingleValueSerializer<&mut S>),

Adds an arbitrary JSON object to this object.

Arguments

• key - the key for the field
• encoder - A closure that encodes a single value into the field.

Examples

let mut obj = ser.object();
obj.complex_field("numbers", |mut ser| {
    let mut arr = ser.array();
    arr.add(1);
    arr.add(2);
    arr.add("three");
});
obj.end()

pub fn object_field<K: Key>(&mut self, key: K) -> ObjectWriter<&mut S>

Adds a JSON object field to this object.

Examples

let mut obj = ser.object();
obj.field("kitten", true);
obj.field("cuteness", 10.0);

let mut bed = obj.object_field("bed");
bed.field("cozy", true);
bed.field("wear_and_tear", 2.0);
bed.end();

obj.end();

pub fn array_field<K: Key>(&mut self, key: K) -> ArrayWriter<&mut S>

Adds a JSON array field to this object.

Examples

let mut arr = ser.array();

let mut obj = arr.add_object();
obj.field("kitten", true);
obj.field("cuteness", 10.0);

let mut toys = obj.array_field("toys");
toys.extend(&["mouse", "ball", "string", "box", "scratcher"]);
toys.end();

obj.end();

arr.end();

pub fn end(self)
