Implementations§

source§

impl Json

source

pub fn from_reader(rdr: &mut dyn Read) -> Result<Self, BuilderError>

Decodes a json value from an &mut io::Read

source

pub fn from_str(s: &str) -> Result<Self, BuilderError>

Decodes a json value from a string

source

pub fn pretty(&self) -> PrettyJson<'_>

Borrow this json object as a pretty object to generate a pretty representation for it via Display.

source

pub fn find<'a>(&'a self, key: &str) -> Option<&'a Json>

If the Json value is an Object, returns the value associated with the provided key. Otherwise, returns None.

source

pub fn find_path<'a>(&'a self, keys: &[&str]) -> Option<&'a Json>

Attempts to get a nested Json Object for each key in keys. If any key is found not to exist, find_path will return None. Otherwise, it will return the Json value associated with the final key.

source

pub fn search<'a>(&'a self, key: &str) -> Option<&'a Json>

If the Json value is an Object, performs a depth-first search until a value associated with the provided key is found. If no value is found or the Json value is not an Object, returns None.

source

pub fn is_object<'a>(&'a self) -> bool

Returns true if the Json value is an Object. Returns false otherwise.

source

pub fn as_object<'a>(&'a self) -> Option<&'a Object>

If the Json value is an Object, returns a reference to the associated BTreeMap. Returns None otherwise.

source

pub fn as_object_mut<'a>(&'a mut self) -> Option<&'a mut Object>

If the Json value is an Object, returns a mutable reference to the associated BTreeMap. Returns None otherwise.

source

pub fn into_object(self) -> Option<Object>

If the Json value is an Object, returns the associated BTreeMap. Returns None otherwise.

source

pub fn is_array<'a>(&'a self) -> bool

Returns true if the Json value is an Array. Returns false otherwise.

source

pub fn as_array<'a>(&'a self) -> Option<&'a Array>

If the Json value is an Array, returns a reference to the associated vector. Returns None otherwise.

source

pub fn as_array_mut<'a>(&'a mut self) -> Option<&'a mut Array>

If the Json value is an Array, returns a mutable reference to the associated vector. Returns None otherwise.

source

pub fn into_array(self) -> Option<Array>

If the Json value is an Array, returns the associated vector. Returns None otherwise.

source

pub fn is_string<'a>(&'a self) -> bool

Returns true if the Json value is a String. Returns false otherwise.

source

pub fn as_string<'a>(&'a self) -> Option<&'a str>

If the Json value is a String, returns the associated str. Returns None otherwise.

source

pub fn is_number(&self) -> bool

Returns true if the Json value is a Number. Returns false otherwise.

source

pub fn is_i64(&self) -> bool

Returns true if the Json value is a i64. Returns false otherwise.

source

pub fn is_u64(&self) -> bool

Returns true if the Json value is a u64. Returns false otherwise.

source

pub fn is_f64(&self) -> bool

Returns true if the Json value is a f64. Returns false otherwise.

source

pub fn as_i64(&self) -> Option<i64>

If the Json value is a number, return or cast it to a i64. Returns None otherwise.

source

pub fn as_u64(&self) -> Option<u64>

If the Json value is a number, return or cast it to a u64. Returns None otherwise.

source

pub fn as_f64(&self) -> Option<f64>

If the Json value is a number, return or cast it to a f64. Returns None otherwise.

source

pub fn is_boolean(&self) -> bool

Returns true if the Json value is a Boolean. Returns false otherwise.

source

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

If the Json value is a Boolean, returns the associated bool. Returns None otherwise.

source

pub fn is_null(&self) -> bool

Returns true if the Json value is a Null. Returns false otherwise.

source

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

If the Json value is a Null, returns (). Returns None otherwise.
