Struct swc_ecma_transforms_testing::Tester

pub struct Tester<'a> {
    pub cm: Lrc<SourceMap>,
    pub handler: &'a Handler,
    pub comments: Rc<SingleThreadedComments>,
}

Fields

cm: Lrc<SourceMap>

handler: &'a Handler

comments: Rc<SingleThreadedComments>

This will be changed to SingleThreadedComments once cargo-mono supports correct bumping logic, or we need to make a breaking change in a upstream crate of this crate.

Although type is Rc<SingleThreadedComments>, it’s fine to clone SingleThreadedComments without Rc.
