Implementations

impl ViewState

pub fn empty() -> ViewState

Returns an empty set of flags.

pub fn all() -> ViewState

Returns the set containing all flags.

pub fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

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

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

pub fn from_bits_truncate(bits: u32) -> ViewState

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

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

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

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

Returns the left flags, but with all the right flags toggled.

type Output = ViewState

The resulting type after applying the ^ operator.

impl BitXorAssign for ViewState

fn bitxor_assign(&mut self, other: ViewState)

Toggles the set of flags.

impl Clone for ViewState

fn clone(&self) -> ViewState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewState

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

Formats the value using the given formatter.

impl FromIterator<ViewState> for ViewState

fn from_iter<T: IntoIterator<Item = ViewState>>(iterator: T) -> ViewState

Creates a value from an iterator.

impl Hash for ViewState

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 Not for ViewState

fn not(self) -> ViewState

Returns the complement of this set of flags.

type Output = ViewState

The resulting type after applying the ! operator.

impl Ord for ViewState

fn cmp(&self, other: &ViewState) -> 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 for ViewState

fn eq(&self, other: &ViewState) -> 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 ViewState

fn partial_cmp(&self, other: &ViewState) -> 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.

impl Sub for ViewState

fn sub(self, other: ViewState) -> ViewState

Returns the set difference of the two sets of flags.

type Output = ViewState

The resulting type after applying the - operator.

impl SubAssign for ViewState

fn sub_assign(&mut self, other: ViewState)

Disables all flags enabled in the set.

impl Copy for ViewState

impl Eq for ViewState
