pub fn hostname() -> Result<OsString>Expand description
Returns the hostname of the current system.
It is unusual, although technically possible, for this routine to return an error. It is difficult to list out the error conditions, but one such possibility is platform support.
Platform specific behavior
On Windows, this currently uses the “physical DNS hostname” computer name. This may change in the future.
On Unix, this returns the result of the gethostname function from the
libc linked into the program.
