Enum style::stylesheets::origin::Origin

#[repr(u8)]
pub enum Origin {
    UserAgent = 1,
    User = 2,
    Author = 4,
}

Each style rule has an origin, which determines where it enters the cascade.

Implementations

impl Origin

fn from_index(index: i8) -> Option<Self>

Returns an origin that goes in order for index.

This is used for iterating across origins.

fn to_index(self) -> i8

pub fn following_including(self) -> OriginSetIterator

Returns an iterator from this origin, towards all the less specific origins. So for UserAgent, it’d iterate through all origins.

Trait Implementations

impl BitOrAssign<Origin> for OriginSet

fn bitor_assign(&mut self, origin: Origin)

Performs the |= operation.

impl Clone for Origin

fn clone(&self) -> Origin

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Origin

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

Formats the value using the given formatter.

impl From<Origin> for OriginSet

fn from(origin: Origin) -> Self

Converts to this type from the input type.

impl MallocSizeOf for Origin

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 Origin

fn cmp(&self, other: &Origin) -> 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 Origin

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

fn partial_cmp(&self, other: &Origin) -> 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 ToShmem for Origin

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.

impl Copy for Origin

impl Eq for Origin

impl StructuralPartialEq for Origin
