Struct strason::Json

pub struct Json(_);

A "stringly-typed" Json object. That is, either a value (represented as a String), or an object (represented as a map from Strings to Jsons).

Methods

impl Json

pub fn from_iter<I: Iterator<Item = Result<u8>>>(it: I) -> Result<Json, Error>

Construct a Json object by parsing a byte iterator, e.g. from a Reader

pub fn from_str(s: &str) -> Result<Json, Error>

Construct a Json object by parsing a string

pub fn from_reader<R: Read>(r: R) -> Result<Json, Error>

Construct a Json object from a reader

pub fn from_serialize<T: Serialize>(val: T) -> Result<Json, Error>

Converts something serializable to a Json object

pub fn null(&self) -> Option<()>

Returns a null, if this is a null

pub fn bool(&self) -> Option<bool>

Returns the value, if this is a boolean

pub fn num(&self) -> Option<&str>

Returns the value, if this is a number

pub fn string(&self) -> Option<&str>

Returns the value, if this is a string

pub fn array(&self) -> Option<&[Json]>

Returns the value, if this is an array

pub fn object(&self) -> Option<&[(String, Json)]>

Returns the value, if this is an object

pub fn get(&self, index: &str) -> Option<&Json>

Obtain a reference to a specified member, if this is an object

pub fn len(&self) -> usize

Return the number of subobjects this object represents (so a count for Arrays and Objects). NOT a string length.

pub fn is_empty(&self) -> bool

Return whether the object is empty, if it is a collection

pub fn write_to<W: Write>(&self, w: W) -> Result<()>

Reserialize the object into a writer

pub fn to_bytes(&self) -> Vec<u8>

Serialize the object to byte array

pub fn into_deserialize<'a, T: Deserialize<'a>>(self) -> Result<T, Error>

Convert the Json object to something deserializable
