Struct nix::unistd::Gid

pub struct Gid(_);

Group identifier

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

Implementations

impl Gid

pub const fn from_raw(gid: gid_t) -> Self

Creates Gid from raw gid_t.

pub fn current() -> Self

Returns Gid of calling process. This is practically a more Rusty alias for getgid.

pub fn effective() -> Self

Returns effective Gid of calling process. This is practically a more Rusty alias for getegid.

pub const fn as_raw(self) -> gid_t

Get the raw gid_t wrapped by self.

Trait Implementations

impl Clone for Gid

fn clone(&self) -> Gid

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Gid

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

Formats the value using the given formatter.

impl Display for Gid

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

Formats the value using the given formatter.

impl From<Gid> for gid_t

fn from(gid: Gid) -> Self

Converts to this type from the input type.

impl From<u32> for Gid

fn from(gid: gid_t) -> Self

Converts to this type from the input type.

impl Hash for Gid

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Gid> for Gid

fn eq(&self, other: &Gid) -> 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.
