Can you add some examples of AST modifications? Convenient for us to implement some simple functions on the frontend of Rust when we are just starting out

Implementation function: Modify AST, wrap the value declared by the variable with a function named "t",
for example: let value = "text" is modified to let value = t("text")

I am currently stuck in the step of replacing nodes

You can't mutate the AST because expr is not mutable. Only properties on ImportParser are mutable.

ok, thanks. Can you provide a minimum example of modifying a node? I searched for the source code and resources online, but couldn't find them. I am learning Rust and trying to use OXC to implement some small tools and functions.

If you're writing your own code and this isn't an oxc linter/transformer/etc, you should use the VisitMut trait instead of Visit. This allows the node to be mutable.

Okay, thank you. I'll go take a look
