Methods

impl Json[src]

pub fn pretty(&self) -> PrettyJson[src]

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

pub fn find(&self, key: &str) -> Option<&Json>[src]

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

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

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.

pub fn search(&self, key: &str) -> Option<&Json>[src]

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.

pub fn is_object(&self) -> bool[src]

Returns true if the Json value is an Object.

pub fn as_object(&self) -> Option<&Object>[src]

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

pub fn is_array(&self) -> bool[src]

Returns true if the Json value is an Array.

pub fn as_array(&self) -> Option<&Array>[src]

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

pub fn is_string(&self) -> bool[src]

Returns true if the Json value is a String.

pub fn as_string(&self) -> Option<&str>[src]

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

pub fn is_number(&self) -> bool[src]

Returns true if the Json value is a Number.

pub fn is_i64(&self) -> bool[src]

Returns true if the Json value is a i64.

pub fn is_u64(&self) -> bool[src]

Returns true if the Json value is a u64.

pub fn is_f64(&self) -> bool[src]

Returns true if the Json value is a f64.

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

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

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

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

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

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

pub fn is_boolean(&self) -> bool[src]

Returns true if the Json value is a Boolean.

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

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

pub fn is_null(&self) -> bool[src]

Returns true if the Json value is a Null.

pub fn as_null(&self) -> Option<()>[src]

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