The unit of a <length> value. Note that if any new font-relative value is added here, custom_properties::NonCustomReferences::from_unit must also be updated. Consult the comment in that function as to why.

The variants are grouped (absolute, font-relative, viewport, container, servo-internal) so that is_* predicates can be implemented with simple range checks.

Implementations

impl LengthUnit

pub fn as_str(self) -> &'static str

Returns this unit as a string.

pub fn is_absolute(self) -> bool

Whether this is an absolute length unit (px, in, cm, mm, q, pt, pc).

pub fn is_font_relative(self) -> bool

Whether this is a font-relative unit.

pub fn is_viewport_percentage(self) -> bool

Whether this is a viewport-percentage unit.

pub fn is_container_relative(self) -> bool

Whether this is a container-relative unit.

fn sort_key(self) -> SortKey

Returns the sort key for this unit. Must not be called for the internal ServoCharacterWidth unit.

Trait Implementations

impl Clone for LengthUnit

fn clone(&self) -> LengthUnit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LengthUnit

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

Formats the value using the given formatter.

impl MallocSizeOf for LengthUnit

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 PartialEq for LengthUnit

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

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

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

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

impl Copy for LengthUnit

impl Eq for LengthUnit

impl StructuralPartialEq for LengthUnit
