Implementations

impl Permissions

pub const fn new() -> Self

Create a new empty Permissions struct

impl Permissions

pub const fn mask(&self) -> u32

Convert into mode_t representation.

pub const fn from_mask(from: u32) -> Self

Convert from mode_t representation.

pub const fn add_mask(self, class: User, bit: Bit) -> Self

Consume and add a mask.

Usage

For builder pattern

pub const fn remove_mask(self, class: User, bit: Bit) -> Self

Consume and remove a mask.

Usage

For builder pattern

pub const fn has_mask(&self, class: User, bit: Bit) -> bool

Returns true if the specified mode mask is all present

Trait Implementations

impl AsRef<Permissions> for Permissions

fn as_ref(&self) -> &Permissions

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<Permissions> for u32

fn as_ref(&self) -> &Permissions

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<Permissions> for u32

fn borrow(&self) -> &Permissions

Immutably borrows from an owned value.

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 Default for Permissions

fn default() -> Self

Returns the “default value” for a type.

impl Display for Permissions

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

Formats the value using the given formatter.

impl From<Permissions> for u32

fn from(from: Permissions) -> Self

Converts to this type from the input type.

impl From<u32> for Permissions

fn from(from: u32) -> Self

Converts to this type from the input type.

impl Hash for Permissions

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Permissions

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq<Permissions> for u32

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.

impl PartialEq<u32> for Permissions

fn eq(&self, other: &u32) -> 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.

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.

impl PartialOrd for Permissions

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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