Struct Permission

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

Represents a permission.

The permission can be read, write, and execute.

Examples

use file_system::Permission_type;

let read = Permission_type::Read_only;
let write = Permission_type::Write_only;
let execute = Permission_type::Execute_only;

assert!(read.get_read() && !read.get_write() && !read.get_execute());
assert!(!write.get_read() && write.get_write() && !write.get_execute());
assert!(!execute.get_read() && !execute.get_write() && execute.get_execute());

pub const fn new(read: bool, write: bool, execute: bool) -> Self

Creates a new permission.

pub fn set_read(self, read: bool) -> Self

Sets the read permission.

pub fn set_write(self, write: bool) -> Self

Sets the write permission.

pub fn set_execute(self, execute: bool) -> Self

Sets the execute permission.

pub const fn get_read(&self) -> bool

Gets the read permission.

pub const fn get_write(&self) -> bool

Gets the write permission.

pub const fn get_execute(&self) -> bool

Gets the execute permission.

pub const fn to_unix(&self) -> u8

Converts the permission to a Unix permission.

pub fn include(&self, other: Self) -> bool

pub fn from_unix(unix: u8) -> Option<Self>

Creates a permission from a Unix permission.

Trait Implementations

impl Clone for Permission

fn clone(&self) -> Permission

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Permission

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

Formats the value using the given formatter.

impl Display for Permission

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

Formats the value using the given formatter.

impl PartialEq for Permission

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