What's wrong with this Rust?

/*
Aside from the panics, and the fact that the API currently requires first a call to new, then select_entry(),
how do I fix the lifetime issues:

error: lifetime may not live long enough
   --> src/sigmf.rs:226:43

221 |     pub fn select_entry(&mut self, filename: &str) -> Result<()> {
    |                         - let's call the lifetime of this reference `'1`

    |                                           ^^^^^^^^^^^^^^^ cast requires that `'1` must outlive `'static`
