Implementations

impl DevicePermissions

pub fn to_char(&self) -> char

Convert a DevicePermissions into the character that the kernel recognizes.

pub fn from_char(c: char) -> Option<DevicePermissions>

Convert a char to a DevicePermission if there is such a mapping.

pub fn is_valid(s: &str) -> bool

Checks whether the string is a valid descriptor of DevicePermissions.

pub fn all() -> Vec<DevicePermissions>

Returns a Vec will all the permissions that a device can have.

pub fn from_str(s: &str) -> Result<Vec<DevicePermissions>>

Convert a string into DevicePermissions.

Trait Implementations

impl Clone for DevicePermissions

fn clone(&self) -> DevicePermissions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DevicePermissions

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

Formats the value using the given formatter.

impl PartialEq for DevicePermissions

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