Implementations

impl Descriptors

pub fn get(&self, id: DescriptorId, dest: &mut CssStringWriter) -> Result

Gets a descriptor in CSS syntax.

pub fn set<'i, 't>( &mut self, id: DescriptorId, context: &ParserContext<'_>, input: &mut Parser<'i, 't>, ) -> Result<bool, ParseError<'i>>

Parses a given descriptor. Returns whether the descriptor changed.

pub fn remove(&mut self, id: DescriptorId) -> bool

Removes a descriptor. Returns true if it used to be set.

pub fn len(&self) -> usize

Returns the count of set descriptors.

pub fn at(&self, i: usize) -> Option<DescriptorId>

Returns the descriptor at position i.

Trait Implementations

impl Clone for Descriptors

fn clone(&self) -> Descriptors

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Descriptors

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

Formats the value using the given formatter.

impl Default for Descriptors

fn default() -> Descriptors

Returns the “default value” for a type.

impl MallocSizeOf for Descriptors

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 Descriptors

fn eq(&self, other: &Descriptors) -> 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 ToCss for Descriptors

fn to_css<W>(&self, dest: &mut CssWriter<'_, W>) -> Result

where W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

fn to_css_cssstring(&self) -> String

Serialize self in CSS syntax and return a CssString.

impl ToShmem for Descriptors

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

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

impl StructuralPartialEq for Descriptors
