Struct Permissions

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

Represents the permissions of a file or directory.

The permissions are divided into three groups: user, group, and others. Each group has three permissions: read, write, and execute.

Examples

use file_system::{Permissions_type, Permission_type, Special_type};

let user = Permission_type::new(true, false, false); // Read only
let group = Permission_type::new(false, true, false); // Write only
let others = Permission_type::new(false, false, true); // Execute only
let special = Special_type::new(true, false, true); // Sticky and set user identifier

let permissions = Permissions_type::new(user, group, others, special);

assert_eq!(permissions.get_user(), user);
assert_eq!(permissions.get_group(), group);
assert_eq!(permissions.get_others(), others);
assert_eq!(permissions.get_special(), special);

Implementations

impl Permissions

pub const NONE: Self

pub const ALL_FULL: Self

pub const ALL_READ_WRITE: Self

pub const USER_FULL: Self

pub const USER_READ_WRITE: Self

pub const EXECUTABLE: Self

pub const fn new( user: Permission, group: Permission, others: Permission, special: Special, ) -> Self

Creates a new permission.

pub const fn new_default(type: Kind) -> Self

Creates a new permission with read access for user. No access for group and others.

pub fn set_user(self, user: Permission) -> Self

Sets the permission for the user.

pub fn set_group(self, group: Permission) -> Self

Sets the permission for the group.

pub fn set_others(self, others: Permission) -> Self

Sets the permission for others.

pub fn set_special(self, special: Special) -> Self

Sets the special permissions.

pub fn get_user(&self) -> Permission

Gets the permission for the user.

pub fn get_group(&self) -> Permission

Gets the permission for the group.

pub fn get_others(&self) -> Permission

Gets the permission for others.

pub fn get_special(&self) -> Special

Gets the special permissions.

pub const fn from_octal(unix: u16) -> Option<Self>

Converts the permission to a Unix permission.

pub const fn as_u16(&self) -> u16

Converts the permission to a Unix permission.

Trait Implementations

impl Clone for Permissions

fn clone(&self) -> Permissions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Permissions

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

Formats the value using the given formatter.

impl Display for Permissions

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

Formats the value using the given formatter.

impl PartialEq for Permissions

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

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

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

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