Sourcepub fn get<I>(&self, index: I) -> Option<&Value>where
I: Index,
pub fn get<I>(&self, index: I) -> Option<&Value>where
I: Index,
Index into a JSON array or map. A string index can be used to access a value in a map, and a usize index can be used to access an element of an array.
Returns None if the type of self does not match the type of the
index, for example if the index is a string and self is an array or a
number. Also returns None if the given key does not exist in the map
or the given index is not within the bounds of the array.
let object = json!({ "A": 65, "B": 66, "C": 67 });
assert_eq!(*object.get("A").unwrap(), json!(65));
let array = json!([ "A", "B", "C" ]);
assert_eq!(*array.get(2).unwrap(), json!("C"));
assert_eq!(array.get("A"), None);Square brackets can also be used to index into a value in a more concise
way. This returns Value::Null in cases where get would have returned
None.
let object = json!({
"A": ["a", "á", "à"],

Returns true if the Value is an Object. Returns false otherwise.
For any Value on which is_object returns true, as_object and
as_object_mut are guaranteed to return the map representation of the
object.

assert_eq!(v["b"].as_object(), None);Sourcepub fn is_array(&self) -> bool
pub fn is_array(&self) -> bool
Returns true if the Value is an Array. Returns false otherwise.
For any Value on which is_array returns true, as_array and

Returns true if the Value is a String. Returns false otherwise.
For any Value on which is_string returns true, as_str is guaranteed
to return the string slice.
let v = json!({ "a": "some string", "b": false });
assert!(v["a"].is_string());
// The boolean `false` is not a string.
assert!(!v["b"].is_string());Sourcepub fn as_str(&self) -> Option<&str>
pub fn as_str(&self) -> Option<&str>
If the Value is a String, returns the associated str. Returns None
otherwise.

assert_eq!(v["a"].as_str(), Some("some string"));
// The boolean `false` is not a string.

Returns true if the Value is a Number. Returns false otherwise.

// The string `"2"` is a string, not a number.
assert!(!v["b"].is_number());Sourcepub fn as_number(&self) -> Option<&Number>
pub fn as_number(&self) -> Option<&Number>
If the Value is a Number, returns the associated Number. Returns
None otherwise.

// The string `"4"` is not a number.
assert_eq!(v["d"].as_number(), None);Sourcepub fn is_i64(&self) -> bool
pub fn is_i64(&self) -> bool
Returns true if the Value is an integer between i64::MIN and
i64::MAX.
For any Value on which is_i64 returns true, as_i64 is guaranteed to
return the integer value.
let big = i64::max_value() as u64 + 10;
let v = json!({ "a": 64, "b": big, "c": 256.0 });
assert!(v["a"].is_i64());
// Greater than i64::MAX.

// Numbers with a decimal point are not considered integers.
assert!(!v["c"].is_i64());Sourcepub fn is_u64(&self) -> bool
pub fn is_u64(&self) -> bool
Returns true if the Value is an integer between zero and u64::MAX.
For any Value on which is_u64 returns true, as_u64 is guaranteed to
return the integer value.
let v = json!({ "a": 64, "b": -64, "c": 256.0 });
assert!(v["a"].is_u64());
// Negative integer.
assert!(!v["b"].is_u64());
// Numbers with a decimal point are not considered integers.
assert!(!v["c"].is_u64());Sourcepub fn is_f64(&self) -> bool
pub fn is_f64(&self) -> bool
Returns true if the Value is a number that can be represented by f64.
For any Value on which is_f64 returns true, as_f64 is guaranteed to
return the floating point value.
Currently this function returns true if and only if both is_i64 and
is_u64 return false but this is not a guarantee in the future.
let v = json!({ "a": 256.0, "b": 64, "c": -64 });

If the Value is an integer, represent it as i64 if possible. Returns
None otherwise.

assert_eq!(v["c"].as_f64(), Some(-64.0));Sourcepub fn is_boolean(&self) -> bool
pub fn is_boolean(&self) -> bool
Returns true if the Value is a Boolean. Returns false otherwise.
For any Value on which is_boolean returns true, as_bool is
guaranteed to return the boolean value.
let v = json!({ "a": false, "b": "false" });

// The string `"false"` is a string, not a boolean.
assert!(!v["b"].is_boolean());Sourcepub fn as_bool(&self) -> Option<bool>

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

// The string `"false"` is a string, not a boolean.
assert_eq!(v["b"].as_bool(), None);Sourcepub fn is_null(&self) -> bool
pub fn is_null(&self) -> bool
Returns true if the Value is a Null. Returns false otherwise.
For any Value on which is_null returns true, as_null is guaranteed
to return Some(()).
let v = json!({ "a": null, "b": false });
assert!(v["a"].is_null());
// The boolean `false` is not null.
assert!(!v["b"].is_null());Sourcepub fn as_null(&self) -> Option<()>
pub fn as_null(&self) -> Option<()>
If the Value is a Null, returns (). Returns None otherwise.
let v = json!({ "a": null, "b": false });
assert_eq!(v["a"].as_null(), Some(()));
// The boolean `false` is not null.
assert_eq!(v["b"].as_null(), None);Sourcepub fn pointer(&self, pointer: &str) -> Option<&Value>
pub fn pointer(&self, pointer: &str) -> Option<&Value>
Looks up a value by a JSON Pointer.
JSON Pointer defines a string syntax for identifying a specific value within a JavaScript Object Notation (JSON) document.
A Pointer is a Unicode string with the reference tokens separated by /.
Inside tokens / is replaced by ~1 and ~ is replaced by ~0. The
addressed value is returned and if there is no such value None is
returned.
For more information read RFC6901.
§Examples
let data = json!({
"x": {
"y": ["z", "zz"]
}
});
assert_eq!(data.pointer("/x/y/1").unwrap(), &json!("zz"));
assert_eq!(data.pointer("/a/b/c"), None);Trait Implementations§
