[asukaminato0721]

ok, I find the problem.

opendal/core/src/layers/blocking.rs

Line 216 in 7455995

async fn presign(&self, path: &str, args: OpPresign) -> Result<RpPresign> {

the origin crate use &str so

1. change the whole crate to use AsRef<Path>, too many changes.
2. do the type change on python binding, I prefer this.
