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: Targets) -> 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: Targets) -> ColorFallbackKind

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

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

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<'de: 'i, 'i> Deserialize<'de> for Image<'i>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'any, 'i> IntoOwned<'any> for Image<'i>

fn into_owned(self) -> Self::Owned

Consumes the value and returns an owned clone.

type Owned = Image<'any>

A variant of Self with a new lifetime.

impl<'i> IsCompatible for Image<'i>

fn is_compatible(&self, browsers: Browsers) -> bool

Returns whether the value is compatible with all of the given browser targets.

impl<'i> JsonSchema for Image<'i>

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

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 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> Serialize for Image<'i>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

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: ?Sized + Visitor<'i, __T>> Visit<'i, __T, __V> for Image<'i>

const CHILD_TYPES: VisitTypes = _

Available on crate feature visitor only.

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) -> Result<(), __V::Error>

Available on crate feature visitor only.

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) -> Result<(), __V::Error>

Available on crate feature visitor only.

Visit the children of this value.
