[−][src]Struct js_sys::JSON
The JSON
object contains methods for parsing JavaScript Object
Notation (JSON) and converting values to JSON. It
can't be called or constructed, and aside from its two method
properties, it has no interesting functionality of its own.
Methods
impl JSON
[src]
pub fn parse(text: &str) -> Result<JsValue, JsValue>
[src]
The JSON.parse()
method parses a JSON string, constructing the
JavaScript value or object described by the string.
impl JSON
[src]
pub fn stringify(obj: &JsValue) -> Result<JsString, JsValue>
[src]
The JSON.stringify()
method converts a JavaScript value to a JSON string.
impl JSON
[src]
pub fn stringify_with_replacer(
obj: &JsValue,
replacer: &JsValue
) -> Result<JsString, JsValue>
[src]
obj: &JsValue,
replacer: &JsValue
) -> Result<JsString, JsValue>
The JSON.stringify()
method converts a JavaScript value to a JSON string.
The replacer
argument is a function that alters the behavior of the stringification
process, or an array of String and Number objects that serve as a whitelist
for selecting/filtering the properties of the value object to be included
in the JSON string. If this value is null or not provided, all properties
of the object are included in the resulting JSON string.
impl JSON
[src]
pub fn stringify_with_replacer_and_space(
obj: &JsValue,
replacer: &JsValue,
space: &JsValue
) -> Result<JsString, JsValue>
[src]
obj: &JsValue,
replacer: &JsValue,
space: &JsValue
) -> Result<JsString, JsValue>
The JSON.stringify()
method converts a JavaScript value to a JSON string.
The replacer
argument is a function that alters the behavior of the stringification
process, or an array of String and Number objects that serve as a whitelist
for selecting/filtering the properties of the value object to be included
in the JSON string. If this value is null or not provided, all properties
of the object are included in the resulting JSON string.
The space
argument is a String or Number object that's used to insert white space into
the output JSON string for readability purposes. If this is a Number, it
indicates the number of space characters to use as white space; this number
is capped at 10 (if it is greater, the value is just 10). Values less than
1 indicate that no space should be used. If this is a String, the string
(or the first 10 characters of the string, if it's longer than that) is
used as white space. If this parameter is not provided (or is null), no
white space is used.
Methods from Deref<Target = Object>
pub fn has_own_property(&self, property: &JsValue) -> bool
[src]
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
pub fn is_prototype_of(&self, value: &JsValue) -> bool
[src]
The isPrototypeOf()
method checks if an object exists in another
object's prototype chain.
pub fn property_is_enumerable(&self, property: &JsValue) -> bool
[src]
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
pub fn to_locale_string(&self) -> JsString
[src]
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
pub fn to_string(&self) -> JsString
[src]
The toString()
method returns a string representing the object.
pub fn value_of(&self) -> Object
[src]
The valueOf()
method returns the primitive value of the
specified object.
