How to specify "missing generics" for type as a function parameter?

I am trying to use a shared semaphore using futures_intrusive::sync::GenericSemaphore:

use std::path::Path;
use futures_intrusive::sync::GenericSemaphore;

async fn refresh_file(raster_file: &Path, slr: f64, output_path: &Path, chunk_size: u32, semaphore: &GenericSemaphore) {
    if output_path.exists().not() {
        build_required_windows(&raster_file, slr, chunk_size, output_path, &semaphore).await?;
    }
}

However I get an error:

error[E0107]: missing generics for struct `GenericSemaphore`

It seems like I need to "add missing generic argument", but I am not sure how to proceed. I have tried specifying a Mutex type and other things without success, but I think this probably has a straightforward answer.

You just need to add the generic type parameter that GenericSemaphore expects to the function signature.

async fn refresh_file<T: RawMutex>(
    raster_file: &Path,
    slr: f64,
    output_path: &Path,
    chunk_size: u32,
    semaphore: &GenericSemaphore<T>
) {

Alternatively, using impl syntax (which is sugar for the code above):

async fn refresh_file(
    raster_file: &Path,
    slr: f64,
    output_path: &Path,
    chunk_size: u32,
    semaphore: &GenericSemaphore<impl RawMutex>
) {
