Implementations
impl Json
[src]
impl Json
[src]pub fn pretty(&self) -> PrettyJson<'_>
[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]
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]
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]
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 as_object(&self) -> Option<&Object>
[src]
pub fn as_object(&self) -> Option<&Object>
[src]If the Json value is an Object
, returns the associated BTreeMap
;
returns None
otherwise.
pub fn as_array(&self) -> Option<&Array>
[src]
pub fn as_array(&self) -> Option<&Array>
[src]If the Json value is an Array
, returns the associated vector;
returns None
otherwise.
pub fn as_string(&self) -> Option<&str>
[src]
pub fn as_string(&self) -> Option<&str>
[src]If the Json value is a String
, returns the associated str
;
returns None
otherwise.
pub fn as_i64(&self) -> Option<i64>
[src]
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]
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]
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]
pub fn is_boolean(&self) -> bool
[src]Returns true
if the Json value is a Boolean
.
pub fn as_boolean(&self) -> Option<bool>
[src]
pub fn as_boolean(&self) -> Option<bool>
[src]If the Json value is a Boolean
, returns the associated bool
;
returns None
otherwise.
