build warning in libgpiod rust bindings with rust 1.83

[Bartosz Golaszewski <brgl@xxxxxxxx>]

Hi Viresh et al,

I noticed the following warning when building libgpiod rust bindings
with rust 1.83:

warning: elided lifetime has a name
  --> libgpiod/src/line_request.rs:234:26
   |
231 |     pub fn read_edge_events<'a>(
   |                             -- lifetime `'a` declared here
...
234 |     ) -> Result<request::Events> {
   |                          ^^^^^^ this elided lifetime gets resolved as `'a`
   |
   = note: `#[warn(elided_named_lifetimes)]` on by default

Could you please take a look as I have no idea what that means?

Best regards
Bartosz
