See my example. I am trying to extract the value of an optional field in the enum. That's where the unwrap comes in.

- masklinn 3y agoWhat I wrote up is the spec-defined desugaring of a single-branch `if let`, aside from desugaring bugs there should be no counter-example. The snippet you link to should be replaceable by something along the lines of match &passages.asset { TranscriptionAsset::Track { artist_name: Some(artist_name), .. } => { metadata .entry(ARTIST_METADATA.to_string()) .or_default() .push(artist_name.clone()); } _ => {} } no `unwrap` needed. I don't know where you got that idea.
