Struct readable_perms::Bit

pub struct Bit { /* fields omitted */ }

The mode mask for each individual class of User.

Notes

No this does not map directly to mode_t. Use User.mode(bits) and User.from_mode(mode).

Implementations

impl Bit

pub const None: Bit

No permissions for this class

pub const Read: Bit

Read permissions for this class

pub const Write: Bit

Write permissions for this class

pub const Execute: Bit

Execute permissions for this class

Notes

For directories, this translates to `can chdir to here'

pub const Mask: Bit

Read + Write + Execute. The whole mask.

pub const fn empty() -> Bit

Returns an empty set of flags

pub const fn all() -> Bit

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<Bit>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> Bit

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> Bit

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: Bit) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: Bit) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: Bit)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Bit)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Bit)

Toggles the specified flags in-place.

pub fn set(&mut self, other: Bit, value: bool)

Inserts or removes the specified flags depending on the passed value.
