Crate js_sys

Bindings to JavaScript’s standard, built-in objects, including their methods and properties.

This does not include any Web, Node, or any other JS environment APIs. Only the things that are guaranteed to exist in the global scope by the ECMAScript standard.

A Note About camelCase, snake_case, and Naming Conventions

JavaScript’s global objects use camelCase naming conventions for functions and methods, but Rust style is to use snake_case. These bindings expose the Rust style snake_case name. Additionally, acronyms within a method name are all lower case, where as in JavaScript they are all upper case. For example, decodeURI in JavaScript is exposed as decode_uri in these bindings.

Re-exports

• pub use wasm_bindgen;

Modules

• Atomics
  The Atomics object provides atomic operations as static methods. They are used with SharedArrayBuffer objects.
• Intl
• 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.
• Math
• Reflect
• WebAssembly

Structs

• Array
• ArrayBuffer
• ArrayIntoIter
  Iterator returned by Array::into_iter
• ArrayIter
  Iterator returned by Array::iter
• AsyncIterator
  Any object that conforms to the JS async iterator protocol. For example, something returned by myObject[Symbol.asyncIterator]().
• BigInt
• BigInt64Array
• BigUint64Array
• Boolean
• DataView
• Date
• Error
• EvalError
• Float32Array
• Float64Array
• Function
• Generator
• Int8Array
• Int16Array
• Int32Array
• IntoIter
  An iterator over the JS Symbol.iterator iteration protocol.
• Iter
  An iterator over the JS Symbol.iterator iteration protocol.
• Iterator
  Any object that conforms to the JS iterator protocol. For example, something returned by myArray[Symbol.iterator]().
• IteratorNext
  The result of calling next() on a JS iterator.
• JsString
• Map
• Number
• Object
• Promise
  The Promise object represents the eventual completion (or failure) of an asynchronous operation, and its resulting value.
• Proxy
• RangeError
  The RangeError object indicates an error when a value is not in the set or range of allowed values.
• ReferenceError
  The ReferenceError object represents an error when a non-existent variable is referenced.
• RegExp
• Set
• SharedArrayBuffer
• Symbol
• SyntaxError
  A SyntaxError is thrown when the JavaScript engine encounters tokens or token order that does not conform to the syntax of the language when parsing code.
• TryFromIntError
  The error type returned when a checked integral type conversion fails.
• TypeError
  The TypeError object represents an error when a value is not of the expected type.
• Uint8Array
• Uint8ClampedArray
• Uint16Array
• Uint32Array
• UriError
  The URIError object represents an error when a global URI handling function was used in a wrong way.
• WeakMap
• WeakSet

Functions

• decode_uri
  The decodeURI() function decodes a Uniform Resource Identifier (URI) previously created by encodeURI or by a similar routine.
• decode_uri_component
  The decodeURIComponent() function decodes a Uniform Resource Identifier (URI) component previously created by encodeURIComponent or by a similar routine.
• encode_uri
  The encodeURI() function encodes a Uniform Resource Identifier (URI) by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two “surrogate” characters).
• encode_uri_component
  The encodeURIComponent() function encodes a Uniform Resource Identifier (URI) component by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two “surrogate” characters).
• escape
  The escape() function computes a new string in which certain characters have been replaced by a hexadecimal escape sequence.
• eval
  The eval() function evaluates JavaScript code represented as a string.
• global
  Returns a handle to the global scope object.
• is_finite
  The global isFinite() function determines whether the passed value is a finite number. If needed, the parameter is first converted to a number.
• parse_float
  The parseFloat() function parses an argument and returns a floating point number, or NaN on error.
• parse_int
  The parseInt() function parses a string argument and returns an integer of the specified radix (the base in mathematical numeral systems), or NaN on error.
• try_iter
  Create an iterator over val using the JS iteration protocol and Symbol.iterator.
• unescape
  The unescape() function computes a new string in which hexadecimal escape sequences are replaced with the character that it represents. The escape sequences might be introduced by a function like escape. Usually, decodeURI or decodeURIComponent are preferred over unescape.
