Struct Js 

pub struct Js { /* private fields */ }

The JavaScript source of a runtime expression, captured at its $(..) site.

The expr! macro builds one of these next to the expression’s Rust value: the source as it reaches the browser, with the values captured from the surrounding Rust scope serialized in place. Nothing is written until the expression is spliced into a view, where the source renders inside a marker comment.

Implementations

fn into_view_parts(self, _cx: &Cx, parts: &mut PartsWriter<'_>)

Appends this attribute value to the view being built.

impl Clone for Js

fn clone(&self) -> Js

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Js

fn fmt(&self, f: &mut Formatter<'_>) -> Result
