Struct nyoom_json::ArrayWriter

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

Serializer for a JSON array.

Implementations

impl<S: JsonBuffer> ArrayWriter<S>

pub fn add(&mut self, val: impl WriteToJson<S>)

Adds a single primitive JSON value to this array.

Examples

let mut arr = ser.array();
arr.add("friends");
arr.add("romans");
arr.add("countrymen");
arr.end();

pub fn extend<V: WriteToJson<S>>(&mut self, vals: impl IntoIterator<Item = V>)

Adds a slice of a JSON primitive to this array.

Examples

let mut arr = ser.array();
arr.extend(&["friends", "romans", "countrymen"]);
arr.end();

pub fn add_complex<F>(&mut self, encoder: F)where F: FnOnce(SingleValueSerializer<&mut S>),

Adds an arbitrary JSON object to this array.

Arguments

• encoder - A closure that encodes a single value into the array.

Examples

let mut arr = ser.array();
arr.add_complex(|mut ser| {
    let mut obj = ser.object();
    obj.field("kitten", true);
    obj.field("cuteness", 10.0);
});
arr.end();

pub fn add_object(&mut self) -> ObjectWriter<&mut S>

Adds a JSON object to this array.

Examples

let mut arr = ser.array();

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

arr.end();

pub fn add_array(&mut self) -> ArrayWriter<&mut S>

Adds a JSON array.. to this array.

Examples

let mut arr = ser.array();

let mut inner_arr = arr.add_array();
inner_arr.extend(&[1,2,3]);
inner_arr.end();

arr.end();

pub fn end(self)

Finishes out the array. Equivalent to drop(arr);

Trait Implementations

impl<S: JsonBuffer> Drop for ArrayWriter<S>

fn drop(&mut self)

Executes the destructor for this type.
