Implementations

impl<'i> Image<'i>

pub fn has_vendor_prefix(&self) -> bool

Returns whether the image includes any vendor prefixed values.

pub fn get_vendor_prefix(&self) -> VendorPrefix

Returns the vendor prefix used in the image value.

pub fn get_necessary_prefixes(&self, targets: Browsers) -> VendorPrefix

Returns the vendor prefixes that are needed for the given browser targets.

pub fn get_prefixed(&self, prefix: VendorPrefix) -> Image<'i>

Returns a vendor prefixed version of the image for the given vendor prefixes.

pub fn get_legacy_webkit(&self) -> Result<Image<'i>, ()>

Returns a legacy -webkit-gradient() value for the image.

May return an error in case the gradient cannot be converted.

pub fn get_necessary_fallbacks(&self, targets: Browsers) -> ColorFallbackKind

Returns the color fallbacks that are needed for the given browser targets.

pub fn get_fallback(&self, kind: ColorFallbackKind) -> Image<'i>

Returns a fallback version of the image for the given color fallback type.

Trait Implementations

impl<'i> Clone for Image<'i>

fn clone(&self) -> Image<'i>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'i> Debug for Image<'i>

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

Formats the value using the given formatter.

impl<'i> Default for Image<'i>

fn default() -> Image<'i>

Returns the “default value” for a type.

impl<'i> Parse<'i> for Image<'i>

fn parse<'t>(
    input: &mut Parser<'i, 't>
) -> Result<Self, ParseError<'i, ParserError<'i>>>

Parse a value of this type using an existing parser.

fn parse_string(input: &'i str) -> Result<Self, ParseError<'i, ParserError<'i>>>

Parse a value from a string.

impl<'i> PartialEq<Image<'i>> for Image<'i>

fn eq(&self, other: &Image<'i>) -> 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<'i> ToCss for Image<'i>

fn to_css<W>(
    &self,
    dest: &mut Printer<'_, '_, '_, W>
) -> Result<(), PrinterError>where
    W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(
    &self,
    options: PrinterOptions<'_>
) -> Result<String, PrinterError>

Serialize self in CSS syntax and return a string.

impl<'i, __T: Visit<'i, __T, __V>, __V: Visitor<'i, __T>> Visit<'i, __T, __V> for Image<'i>

const CHILD_TYPES: VisitTypes = _

The types of values contained within this value and its children. This is used to skip branches that don’t have any values requested by the Visitor.

fn visit(&mut self, visitor: &mut __V)

Visits the value by calling an appropriate method on the Visitor. If no corresponding visitor method exists, then the children are visited.

fn visit_children(&mut self, visitor: &mut __V)

Visit the children of this value.
