}Methods
impl Restrictions
fn empty() -> Restrictions
Returns an empty set of flags.
fn all() -> Restrictions
Returns the set containing all flags.
fn bits(&self) -> u8
Returns the raw value of the flags currently stored.
fn from_bits(bits: u8) -> Option<Restrictions>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
fn from_bits_truncate(bits: u8) -> Restrictions
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
fn is_empty(&self) -> bool
Returns true if no flags are currently stored.
fn is_all(&self) -> bool
Returns true if all flags are currently set.
fn intersects(&self, other: Restrictions) -> bool
Returns true if there are flags common to both self and other.
fn contains(&self, other: Restrictions) -> bool
Returns true all of the flags in other are contained within self.
fn insert(&mut self, other: Restrictions)
Inserts the specified flags in-place.
fn remove(&mut self, other: Restrictions)
Removes the specified flags in-place.
fn toggle(&mut self, other: Restrictions)
Toggles the specified flags in-place.
Trait Implementations
impl BitOr for Restrictions
type Output = Restrictions
fn bitor(self, other: Restrictions) -> Restrictions
Returns the union of the two sets of flags.
impl BitXor for Restrictions
type Output = Restrictions
fn bitxor(self, other: Restrictions) -> Restrictions
Returns the left flags, but with all the right flags toggled.
impl BitAnd for Restrictions
type Output = Restrictions
fn bitand(self, other: Restrictions) -> Restrictions
Returns the intersection between the two sets of flags.
impl Sub for Restrictions
type Output = Restrictions
fn sub(self, other: Restrictions) -> Restrictions
Returns the set difference of the two sets of flags.
impl Not for Restrictions
type Output = Restrictions
fn not(self) -> Restrictions
Returns the complement of this set of flags.
