Struct style::stylesheets::viewport_rule::ViewportRule

pub struct ViewportRule {
    pub declarations: Vec<ViewportDescriptorDeclaration>,
}

A @viewport rule.

Fields

declarations: Vec<ViewportDescriptorDeclaration>

The declarations contained in this @viewport rule.

Implementations

impl ViewportRule

pub fn parse<'i, 't>(
    context: &ParserContext<'_>,
    input: &mut Parser<'i, 't>
) -> Result<Self, ParseError<'i>>

Parse a single @viewport rule.

TODO(emilio): This could use the Parse trait now.

impl ViewportRule

pub fn from_meta(content: &str) -> Option<ViewportRule>

fn parse_meta_property<'a>(
    content: &'a str,
    iter: &mut Enumerate<Chars<'a>>,
    start: usize
) -> Option<(&'a str, &'a str)>

Trait Implementations

impl Clone for ViewportRule

fn clone(&self) -> ViewportRule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ViewportRule

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

Formats the value using the given formatter.

impl MallocSizeOf for ViewportRule

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<ViewportRule> for ViewportRule

fn eq(&self, other: &ViewportRule) -> 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 ToCssWithGuard for ViewportRule

fn to_css(
    &self,
    _guard: &SharedRwLockReadGuard<'_>,
    dest: &mut CssStringWriter
) -> Result

Serialize self in CSS syntax, writing to dest, using the given lock guard.

fn to_css_string(&self, guard: &SharedRwLockReadGuard<'_>) -> CssString

Serialize self in CSS syntax using the given lock guard and return a string.

impl ToShmem for ViewportRule

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

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