MDN Documentation

This API requires the following crate features to be activated: Node

`pub const TEXT_NODE: u16`[src]

`pub const CDATA_SECTION_NODE: u16`[src]

`pub const NULL: JsValue`[src]

`pub const UNDEFINED: JsValue`[src]

`pub const TRUE: JsValue`[src]

`pub const FALSE: JsValue`[src]

`pub fn as_f64(&self) -> Option<f64>`[src]

Returns the f64 value of this JS value if it’s an instance of a number.

If this JS value is not an instance of a number then this returns None.

`pub fn is_string(&self) -> bool`[src]

Tests whether this JS value is a JS string.

`pub fn as_string(&self) -> Option<String>`[src]

If this JS value is a string value, this function copies the JS string value into wasm linear memory, encoded as UTF-8, and returns it as a Rust String.

To avoid the copying and re-encoding, consider the JsString::try_from() function from js-sys instead.

If this JS value is not an instance of a string or if it’s not valid utf-8 then this returns None.

UTF-16 vs UTF-8

JavaScript strings in general are encoded as UTF-16, but Rust strings are encoded as UTF-8. This can cause the Rust string to look a bit different than the JS string sometimes. For more details see the documentation about the str type which contains a few caveats about the encodings.

`pub fn as_bool(&self) -> Option<bool>`[src]

Returns the bool value of this JS value if it’s an instance of a boolean.

If this JS value is not an instance of a boolean then this returns None.

`pub fn is_null(&self) -> bool`[src]

Tests whether this JS value is null

`pub fn is_undefined(&self) -> bool`[src]

Tests whether this JS value is undefined

`pub fn is_symbol(&self) -> bool`[src]

Tests whether the type of this JS value is symbol

`pub fn is_object(&self) -> bool`[src]

Tests whether typeof self == "object" && self !== null.

`pub fn is_function(&self) -> bool`[src]

Tests whether the type of this JS value is function.

`pub fn is_truthy(&self) -> bool`[src]

Tests whether the value is “truthy”.

`pub fn is_falsy(&self) -> bool`[src]

Tests whether the value is “falsy”.
