Struct leptos::wasm_bindgen::JsValue

pub struct JsValue { /* private fields */ }

Representation of an object owned by JS.

A JsValue doesn’t actually live in Rust right now but actually in a table owned by the wasm-bindgen generated JS glue code. Eventually the ownership will transfer into wasm directly and this will likely become more efficient, but for now it may be slightly slow.

Implementations

impl JsValue

pub const NULL: JsValue = JsValue{ idx: JSIDX_NULL, _marker: marker::PhantomData,}

The null JS value constant.

pub const UNDEFINED: JsValue = JsValue{ idx: JSIDX_UNDEFINED, _marker: marker::PhantomData,}

The undefined JS value constant.

pub const TRUE: JsValue = JsValue{ idx: JSIDX_TRUE, _marker: marker::PhantomData,}

The true JS value constant.

pub const FALSE: JsValue = JsValue{ idx: JSIDX_FALSE, _marker: marker::PhantomData,}

The false JS value constant.

pub fn from_str(s: &str) -> JsValue

Creates a new JS value which is a string.

The utf-8 string provided is copied to the JS heap and the string will be owned by the JS garbage collector.

pub fn from_f64(n: f64) -> JsValue

Creates a new JS value which is a number.

This function creates a JS value representing a number (a heap allocated number) and returns a handle to the JS version of it.

pub fn bigint_from_str(s: &str) -> JsValue

Creates a new JS value which is a bigint from a string representing a number.

This function creates a JS value representing a bigint (a heap allocated large integer) and returns a handle to the JS version of it.

pub fn from_bool(b: bool) -> JsValue

Creates a new JS value which is a boolean.

This function creates a JS object representing a boolean (a heap allocated boolean) and returns a handle to the JS version of it.

pub fn undefined() -> JsValue

Creates a new JS value representing undefined.

pub fn null() -> JsValue

Creates a new JS value representing null.

pub fn symbol(description: Option<&str>) -> JsValue

Creates a new JS symbol with the optional description specified.

This function will invoke the Symbol constructor in JS and return the JS object corresponding to the symbol created.

pub fn from_serde<T>(t: &T) -> Result<JsValue, Error>where
    T: Serialize + ?Sized,

👎Deprecated: causes dependency cycles, use serde-wasm-bindgen or gloo_utils::format::JsValueSerdeExt instead

Creates a new JsValue from the JSON serialization of the object t provided.

This function is deprecated, due to creating a dependency cycle in some circumstances. Use serde-wasm-bindgen or gloo_utils::format::JsValueSerdeExt instead.

This function will serialize the provided value t to a JSON string, send the JSON string to JS, parse it into a JS object, and then return a handle to the JS object. This is unlikely to be super speedy so it’s not recommended for large payloads, but it’s a nice to have in some situations!

Usage of this API requires activating the serde-serialize feature of the wasm-bindgen crate.

Errors

Returns any error encountered when serializing T into JSON.

pub fn into_serde<T>(&self) -> Result<T, Error>where
    T: for<'a> Deserialize<'a>,

👎Deprecated: causes dependency cycles, use serde-wasm-bindgen or gloo_utils::format::JsValueSerdeExt instead

Invokes JSON.stringify on this value and then parses the resulting JSON into an arbitrary Rust value.

This function is deprecated, due to creating a dependency cycle in some circumstances. Use serde-wasm-bindgen or gloo_utils::format::JsValueSerdeExt instead.

This function will first call JSON.stringify on the JsValue itself. The resulting string is then passed into Rust which then parses it as JSON into the resulting value.

Usage of this API requires activating the serde-serialize feature of the wasm-bindgen crate.

Errors

Returns any error encountered when parsing the JSON into a T.

pub fn as_f64(&self) -> Option<f64>

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

Tests whether this JS value is a JS string.

pub fn as_string(&self) -> Option<String>

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>

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.
