Implementations

impl Passwd

pub fn belongs_to(&self) -> Vec<u32, Global>

This is a wrapper function for libc::getgrouplist.

From: <https://man7.org/linux/man-pages/man3/getgrouplist.3.html>

If the number of groups of which user is a member is less than or equal to *ngroups, then the value *ngroups is returned. If the user is a member of more than *ngroups groups, then getgrouplist() returns -1. In this case, the value returned in *ngroups can be used to resize the buffer passed to a further call getgrouplist().

However, on macOS/darwin (and maybe others?) getgrouplist does not update ngroups if ngroups is too small. Therefore, if not updated by getgrouplist, ngroups needs to be increased in a loop until getgrouplist stops returning -1.
