Struct nix::unistd::Uid

source · [−]

pub struct Uid(_);

Expand description

User identifier

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

Implementations

source

impl Uid

source

pub const fn from_raw(uid: uid_t) -> Self

Creates Uid from raw uid_t.

source

pub fn current() -> Self

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

source

pub fn effective() -> Self

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

source

pub const fn is_root(self) -> bool

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

source

pub const fn as_raw(self) -> uid_t

Get the raw uid_t wrapped by self.
