Functions§

catch_unwind: Invokes a closure, capturing the cause of an unwinding panic if one occurs.
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escape: The escape() function computes a new string in which certain characters have been replaced by a hexadecimal escape sequence.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.
swap: Swaps the values at two mutable locations, without deinitializing either one.
take: Replaces dest with the default value of T, returning the previous dest value.
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.
window: Getter for the Window object
zeroed^⚠: Returns the value of type T represented by the all-zero byte-pattern.

Type Aliases§

Closure: Alias for ScopedClosure<'static, T> for backwards compatibility.
EventCallback: Type alias for an event callback closure.

TextNodeBinder
