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.

Implementations

impl Uid

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

Creates Uid from raw uid_t.

pub fn current() -> Self

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

pub fn effective() -> Self

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

pub const fn is_root(self) -> bool

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

pub const fn as_raw(self) -> uid_t

Get the raw uid_t wrapped by self.

Trait Implementations

impl Clone for Uid

fn clone(&self) -> Uid

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Uid

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Uid

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Uid> for uid_t

fn from(uid: Uid) -> Self

Converts to this type from the input type.

impl Hash for Uid

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Uid> for Uid

fn eq(&self, other: &Uid) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
