validation done by parse and safeApply functions of Uri

Hi,

I cannot understand the parse and safeApply functions of Uri

The following unit tests are OK.
import sttp.model.Uri
// scheme:[//[user:password@]host[:port]]path[?query][#fragment]
assert(Uri.safeApply("http://example.com/path?query=123#frag").isRight)
assert(Uri.safeApply("mailto:user@example.com").isRight)
assert(Uri.safeApply("ftp://user:pass@ftp.example.org:21/files").isRight)

But the following unit tests are KO : do I use correctly the API to validate an uri ?
// 1. Missing scheme
assert(Uri.safeApply("example.com/path").isLeft)
// 2. Invalid characters (unescaped)
assert(Uri.safeApply("http://example.com/space here").isLeft)
// 3. Invalid port number
assert(Uri.safeApply("http://example.com:999999/path").isLeft)
// 4. Malformed IPv6 address
assert(Uri.safeApply("http://[2001:db8::12345]/path").isLeft)

regards,

Start with the Uri.parse and Uri.safeApply entry points and run the supplied unit-test cases, comparing the successful examples with the four failing inputs. Determine whether those failures match the API's validation contract; done means the expected behavior for missing schemes, spaces, ports, and malformed IPv6 is clarified or corrected with focused tests.
