Struct nix::unistd::Uid

pub struct Uid(_);

User identifier

Newtype pattern around uid_t (which is just alias). It prevents bugs caused by accidentally passing wrong value.

Methods

impl Uid

fn from_raw(uid: uid_t) -> Self

Creates Uid from raw uid_t.

fn current() -> Self

Returns Uid of calling process. This is practically a more Rusty alias for getuid.

fn effective() -> Self

Returns effective Uid of calling process. This is practically a more Rusty alias for geteuid.

fn is_root(&self) -> bool

Returns true if the Uid represents privileged user - root. (If it equals zero.)
