hurfmt: panics when broken pipe

[jcamiel]

hurlfmt is panicking when pipe is broken:

$ echo 'GET https://hurl.dev' | hurlfmt --out json | aaa
zsh: command not found: aaa
thread 'main' panicked at packages/hurlfmt/src/main.rs:138:18:
writing bytes to console: Os { code: 32, kind: BrokenPipe, message: "Broken pipe" }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Panicking is here =>

hurl/packages/hurlfmt/src/main.rs

Lines 148 to 149 in 4e2f2d1

	file.write_all(bytes.as_slice())
	.expect("writing bytes to file");

Compare with Hurl:

$ echo 'GET https://hurl.dev' | hurl | aaa                     
zsh: command not found: aaa
error: IO Error
  --> -:1:1
   |
 1 | GET https://hurl.dev
   | ^ Broken pipe (os error 32)
   |

hurlfmt should exit with an error message and a status code != 0.

Hi, I created the PR #3701, not sure if its a good fix but also update the original bug description, because the panic is occurring at

hurl/packages/hurlfmt/src/main.rs

Lines 136 to 138 in 4e2f2d1

	handle
	.write_all(bytes.as_slice())
	.expect("writing bytes to console");
