Enum style::stylesheet_set::OriginValidity

pub enum OriginValidity {
    Valid,
    CascadeInvalid,
    FullyInvalid,
}

The validity of the data in a given cascade origin.

Variants

Valid

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

CascadeInvalid

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

FullyInvalid

Everything needs to be rebuilt.

Trait Implementations

impl Clone for OriginValidity

fn clone(&self) -> OriginValidity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for OriginValidity

impl Eq for OriginValidity

impl Ord for OriginValidity

fn cmp(&self, __arg_0: &OriginValidity) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl PartialEq for OriginValidity

fn eq(&self, __arg_0: &OriginValidity) -> 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 !=.

impl PartialOrd for OriginValidity

fn partial_cmp(&self, __arg_0: &OriginValidity) -> 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.

impl MallocSizeOf for OriginValidity

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 Default for OriginValidity

fn default() -> Self

Returns the "default value" for a type.
