`unwrap_or_else_default` -> `unwrap_or_default` and improve resulting lint Resolves rust-lang#10080 (though it doesn't implement exactly what's described there) This PR does the following: 1. Merges `unwrap_or_else_default.rs`'s code into `or_fun_call.rs` 2. Extracts the code to handle `unwrap_or(/* default value */)` and similar, and moves it into `unwrap_or_else_default` 3. Implements the missing functionality from rust-lang#9342, e.g.,, to handle `or_insert_with(Default::default)` 4. Renames `unwrap_or_else_default` to `unwrap_or_default` (since the "new" lint handles both `unwrap_or` and `unwrap_or_else`, it seemed sensible to use the shortened name) This PR is currently two commits. The first implements 1-3, the second implements 4. A word about 2: the `or_fun_call` lint currently produces warnings like the following: ``` error: use of `unwrap_or` followed by a call to `new` --> $DIR/or_fun_call.rs:56:14 | LL | with_new.unwrap_or(Vec::new()); | ^^^^^^^^^^^^^^^^^^^^^ help: try: `unwrap_or_default()` ``` To me, such warnings look like they should come from `unwrap_or_else_default`, not `or_fun_call`, especially since `or_fun_call` is [in the nursery](rust-lang/rust-clippy#9829). --- changelog: Move: Renamed `unwrap_or_else_default` to [`unwrap_or_default`] [rust-lang#10120](rust-lang/rust-clippy#10120) changelog: Enhancement: [`unwrap_or_default`]: Now handles more functions, like `or_insert_with` [rust-lang#10120](rust-lang/rust-clippy#10120) <!-- changelog_checked-->
