Implementations

impl Rule

pub const fn is_qualified_rule(&self) -> bool

Returns true if self is of variant QualifiedRule.

pub fn as_qualified_rule(&self) -> Option<&Box<QualifiedRule>>

Returns Some if self is a reference of variant QualifiedRule, and None otherwise.

pub fn as_mut_qualified_rule(&mut self) -> Option<&mut Box<QualifiedRule>>

Returns Some if self is a mutable reference of variant QualifiedRule, and None otherwise.

pub fn expect_qualified_rule(self) -> Box<QualifiedRule>

where Self: Debug,

Unwraps the value, yielding the content of QualifiedRule.

Panics

Panics if the value is not QualifiedRule, with a panic message including the content of self.

pub fn qualified_rule(self) -> Option<Box<QualifiedRule>>

Returns Some if self is of variant QualifiedRule, and None otherwise.

pub const fn is_at_rule(&self) -> bool

Returns true if self is of variant AtRule.

pub fn as_at_rule(&self) -> Option<&Box<AtRule>>

Returns Some if self is a reference of variant AtRule, and None otherwise.

pub fn as_mut_at_rule(&mut self) -> Option<&mut Box<AtRule>>

Returns Some if self is a mutable reference of variant AtRule, and None otherwise.

pub fn expect_at_rule(self) -> Box<AtRule>

where Self: Debug,

Unwraps the value, yielding the content of AtRule.

Panics

Panics if the value is not AtRule, with a panic message including the content of self.

pub fn at_rule(self) -> Option<Box<AtRule>>

Returns Some if self is of variant AtRule, and None otherwise.

pub const fn is_list_of_component_values(&self) -> bool

Returns true if self is of variant ListOfComponentValues.

pub fn as_list_of_component_values(&self) -> Option<&Box<ListOfComponentValues>>

Returns Some if self is a reference of variant ListOfComponentValues, and None otherwise.

pub fn as_mut_list_of_component_values( &mut self, ) -> Option<&mut Box<ListOfComponentValues>>

Returns Some if self is a mutable reference of variant ListOfComponentValues, and None otherwise.

pub fn expect_list_of_component_values(self) -> Box<ListOfComponentValues>

where Self: Debug,

Unwraps the value, yielding the content of ListOfComponentValues.

Panics

Panics if the value is not ListOfComponentValues, with a panic message including the content of self.

pub fn list_of_component_values(self) -> Option<Box<ListOfComponentValues>>

Returns Some if self is of variant ListOfComponentValues, and None otherwise.

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rule

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

Formats the value using the given formatter.

impl EqIgnoreSpan for Rule

fn eq_ignore_span(&self, other: &Self) -> bool

impl From<Box<AtRule>> for Rule

fn from(v: Box<AtRule>) -> Self

Converts to this type from the input type.

impl From<Box<ListOfComponentValues>> for Rule

fn from(v: Box<ListOfComponentValues>) -> Self

Converts to this type from the input type.

impl From<Box<QualifiedRule>> for Rule

fn from(v: Box<QualifiedRule>) -> Self

Converts to this type from the input type.

impl From<Rule> for ComponentValue

fn from(rule: Rule) -> Self

Converts to this type from the input type.

impl Hash for Rule

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for Rule

fn eq(&self, other: &Rule) -> 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.

fn span(&self) -> Span

Get span of self.

fn span_lo(&self) -> BytePos

fn span_hi(&self) -> BytePos

impl Take for Rule

fn dummy() -> Self

Create a dummy value of this type.

fn take(&mut self) -> Self

fn map_with_mut<F>(&mut self, op: F)

where F: FnOnce(Self) -> Self,

Mutate self using op, which accepts owned data.

impl Eq for Rule

impl StructuralPartialEq for Rule
