Struct coreutils_core::os::group::Group

pub struct Group { /* fields omitted */ }

This struct holds information about a group of UNIX/UNIX-like systems.

Contains sys/types.h group struct attributes as Rust powefull types.

Methods

impl Group

pub fn new() -> Result<Self>

Creates a new Group getting the user group as default.

Errors

If there is a error ocurrence when getting group (C struct) or converting it into Group, an error variant is returned.

pub fn from_gid(id: Gid) -> Result<Self>

Creates a Group using a id to get all attributes.

Errors

If there is a error ocurrence when getting group (C struct) or converting it into Group, an error variant is returned.

pub fn from_name(name: &str) -> Result<Self>

Creates a Group using a name to get all attributes.

Errors

pub fn name(&self) -> &BStr

Returns the Group name.

pub fn id(&self) -> Gid

Returns the Group id.

pub fn passwd(&self) -> &BStr

Returns the Group encrypted password.

pub fn mem(&self) -> &Members

Returns the Group list of members.

Trait Implementations

impl Clone for Group

fn clone(&self) -> Group

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Group

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

Formats the value using the given formatter.

impl Eq for Group

impl From<Group> for group

fn from(gr: Group) -> Self

Performs the conversion.

impl Hash for Group

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,

impl Ord for Group

fn cmp(&self, other: &Group) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Group> for Group

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

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

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

This method tests for !=.

impl PartialOrd<Group> for Group

fn partial_cmp(&self, other: &Group) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Group) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Group) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Group) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Group) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralEq for Group

impl StructuralPartialEq for Group

impl TryFrom<group> for Group

type Error = Error
