How to replace jsx attribute value

[akzhy]

I am trying to write a program to replace the value of jsx className attribute. Right now I have the below code

pub struct AttributeUpdater<'a> {
  pub allocator: &'a Allocator,
  pub ast_builder: AstBuilder<'a>,
}

impl<'a> VisitMut<'a> for AttributeUpdater<'a>
{
  fn visit_jsx_attribute(&mut self, it: &mut oxc_ast::ast::JSXAttribute<'_>) {
    if let JSXAttributeName::Identifier(ident) = &it.name {
      if ident.name == "className" {
        let value = it.value.as_ref().unwrap();

        if let JSXAttributeValue::StringLiteral(string_value) = value {
          let uppercased = string_value.value.to_uppercase();
          let atom = self.allocator.alloc_str(&uppercased);

          // Create new StringLiteral with proper JSX attribute value
          let new_value =
            self
              .ast_builder
              .jsx_attribute_value_string_literal(string_value.span, atom, None);

          it.value = Some(new_value);
         // lifetime may not live long enough
         // assignment requires that `'a` must outlive `'1`
        }
      }
    }
  }
}

However with the above code I am getting a lifetime error when assigning to it.value. How can I properly replace the value?
PS I am fairly new to rust

try

pub struct AttributeUpdater<'a> {
    pub allocator: &'a Allocator,
    pub ast_builder: AstBuilder<'a>,
}

impl<'a> VisitMut<'a> for AttributeUpdater<'a> {
    fn visit_jsx_attribute(&mut self, it: &mut oxc_ast::ast::JSXAttribute<'a>) {
        if let JSXAttributeName::Identifier(ident) = &it.name {
            if ident.name == "className" {
                let value = it.value.as_ref().unwrap();

                if let JSXAttributeValue::StringLiteral(string_value) = value {
                    let uppercased = string_value.value.to_uppercase();
                    let atom = self.allocator.alloc_str(&uppercased);

                    // Create new StringLiteral with proper JSX attribute value
                    let new_value = self.ast_builder.jsx_attribute_value_string_literal(
                        string_value.span,
                        atom,
                        None,
                    );

                    it.value = Some(new_value);
                    // lifetime may not live long enough
                    // assignment requires that `'a` must outlive `'1`
                }
            }
        }
    }
}

the implicit lifetime on JSXAttribute<'_> has been changed to an explicit lifetime a

Damn. I tried everything but that. Thanks for the quick reply, it fixed the issue.

[camc314]

No worries. I'd recommend also taking a look at the code inside oxc_transformer, as there're lots of examples you should be able to copy

Thanks again, I've been looking for some code samples that I could use
