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 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 fn as_raw(self) -> gid_t

Get the raw gid_t wrapped by self.
