Struct Gid 

pub struct Gid(/* private fields */);

gid_t—A Unix group ID.

Implementations

impl Gid

pub const ROOT: Gid

A Gid corresponding to the root group (gid 0).

pub fn from_raw(raw: u32) -> Gid

Converts a RawGid into a Gid.

raw must be the value of a valid Unix group ID, and not -1.

pub const fn from_raw_unchecked(raw: u32) -> Gid

Converts a RawGid into a Gid.

raw must be the value of a valid Unix group ID, and not -1.

pub const fn as_raw(self) -> u32

Converts a Gid into a RawGid.

pub const fn is_root(self) -> bool

Test whether this gid represents the root group (Gid::ROOT).

Trait Implementations

impl Binary for Gid

Formats the value using the given formatter.

impl Clone for Gid

fn clone(&self) -> Gid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Gid

impl Hash for Gid

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

impl Octal for Gid

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

Formats the value using the given formatter.

impl PartialEq for Gid

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

Tests for self and other values to be equal, and is used by ==.

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