Enum style::stylesheet_set::DataValidity

pub enum DataValidity {
    Valid = 0,
    CascadeInvalid = 1,
    FullyInvalid = 2,
}

The validity of the data in a given cascade origin.

Variants

Valid = 0

The origin is clean, all the data already there is valid, though we may have new sheets at the end.

CascadeInvalid = 1

The cascade data is invalid, but not the invalidation data (which is order-independent), and thus only the cascade data should be inserted.

FullyInvalid = 2

Everything needs to be rebuilt.

Trait Implementations

impl Clone for DataValidity

fn clone(&self) -> DataValidity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataValidity

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

Formats the value using the given formatter.

impl Default for DataValidity

fn default() -> Self

Returns the “default value” for a type.

impl MallocSizeOf for DataValidity

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl Ord for DataValidity

fn cmp(&self, other: &DataValidity) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for DataValidity

fn eq(&self, other: &DataValidity) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DataValidity

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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