# Description  Before this PR, you can access rendered error values that are raised in a `try/catch` block by accessing the `rendered` element of the catch error value: ``` $ try { ls nonexist.txt } catch {|e| print "my cool error:" $e.rendered } my cool error: nu::shell::directory_not_found × Directory not found help: /home/rose/nonexist.txt does not exist ``` However, the rendered errors don't include the labels present in the real rendered error, which would look like this: ``` $ ls nonexist.txt Error: nu::shell::directory_not_found × Directory not found ╭─[entry #46:1:4] 1 │ ls nonexist.txt · ──────┬───── · ╰── directory not found ╰──── help: /home/rose/nonexist.txt does not exist ``` After this PR, the rendered error includes the labels: ``` $ try { ls nonexist.txt } catch {|e| print "my cool error:" $e.rendered } my cool error: Error: nu:🐚:directory_not_found × Directory not found ╭─[entry #4:1:10] 1 │ try { ls nonexist.txt } catch {|e| print "my cool error:" $e.rendered } · ──────┬───── · ╰── directory not found ╰──── help: /home/rose/nonexist.txt does not exist ``` This change is accomplished by using the standard error formatting code to render an error. This respects the error theme as before without any extra scaffolding, but it means that e.g., the terminal size is also respected. I think this is fine because the way the error is rendered already changed based on config, and I think that a "rendered" error should give back _exactly_ what would be shown to the user anyway. @fdncred, let me know if you have any concerns with the way this is handled since you were the one who implemented this feature in the first place. # User-Facing Changes  The `rendered` element of the `try`/`catch` error record now includes labels in the error output. # Tests + Formatting  - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting  N/A
