It seems we cannot use `async-backtrace` to create a new layer.
`#[async_backtrace::framed]` will change the `fn read` 's signature.
```rust
impl<A: Accessor> LayeredAccessor for AsyncBacktraceAccessor<A> {
...
#[async_backtrace::framed]
async fn read(&self, path: &str, args: OpRead) -> Result<(RpRead,
Self::Reader)> {
self.inner.read(path, args).await
}
...
}
```
The example code below will give an error `Not all trait items implemented,
missing: read [E0046]`
