Implementations

impl<'i> SupportsCondition<'i>

pub fn and(&mut self, b: &SupportsCondition<'i>)

Combines the given supports condition into this one with an and expression.

pub fn or(&mut self, b: &SupportsCondition<'i>)

Combines the given supports condition into this one with an or expression.

Trait Implementations

impl<'i> Clone for SupportsCondition<'i>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'i> Debug for SupportsCondition<'i>

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

Formats the value using the given formatter.

impl<'de: 'i, 'i> Deserialize<'de> for SupportsCondition<'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 SupportsCondition<'i>

fn into_owned(self) -> Self::Owned

Consumes the value and returns an owned clone.

type Owned = SupportsCondition<'any>

A variant of Self with a new lifetime.

impl<'i> JsonSchema for SupportsCondition<'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(generator: &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 SupportsCondition<'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 SupportsCondition<'i>

fn eq(&self, other: &SupportsCondition<'i>) -> 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<'i> Serialize for SupportsCondition<'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 SupportsCondition<'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 SupportsCondition<'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.
