Trait Implementations

impl<'a> Clone for ComponentValues<'a>

fn clone(&self) -> ComponentValues<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ComponentValues<'a>

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

Formats the value using the given formatter.

impl<'a> DeclarationValue<'a> for ComponentValues<'a>

type ComputedValue = ComponentValues<'a>

fn is_initial(&self) -> bool

Determines if the parsed Self was parsed as the “initial” keyword.

fn is_inherit(&self) -> bool

Determines if the parsed Self was parsed as the “inherit” keyword.

fn is_unset(&self) -> bool

Determines if the parsed Self was parsed as the “unset” keyword.

fn is_revert(&self) -> bool

Determines if the parsed Self was parsed as the “revert” keyword.

fn is_revert_layer(&self) -> bool

Determines if the parsed Self was parsed as the “revert” keyword.

fn needs_computing(&self) -> bool

Determines if the parsed Self is not a valid literal production of the grammar, and instead some of its constituent parts will need additional computation to reify into a known value.

fn parse_custom_declaration_value( p: &mut Parser<'a>, _name: Cursor, ) -> Result<Self>

Like parse() but with the additional context of the name Cursor. This cursor is known to be dashed ident, therefore this should return a Self reflecting a Custom property. Alternatively, if this DeclarationValue disallows custom declarations then this is the right place to return a parse Error.

fn parse_computed_declaration_value( p: &mut Parser<'a>, _name: Cursor, ) -> Result<Self>

Like parse() but with the additional context of the name Cursor. This is only called before verifying that the next token was peeked to be a ComputedValue, therefore this should return a Self reflecting a Computed property. Alternatively, if this DeclarationValue disallows computed declarations then this is the right place to return a parse Error.

fn parse_unknown_declaration_value( p: &mut Parser<'a>, _name: Cursor, ) -> Result<Self>

Like parse() but with the additional context of the name Cursor. This is only called on values that are didn’t parse as either a Custom, Computed or Specified value therefore this should return a Self reflecting an unknown property, or alternatively the right place to return a parse error.

fn valid_declaration_name(_p: &Parser<'a>, _c: Cursor) -> bool

Determines if the given Cursor represents a valid Ident matching a known property name.

fn is_unknown(&self) -> bool

Determines if the parsed Self was parsed as an unknown value.

fn is_custom(&self) -> bool

Determines if the parsed Self was parsed as a Custom value.

fn parse_specified_declaration_value( p: &mut Parser<'a>, _name: Cursor, ) -> Result<Self>

Like parse() but with the additional context of the name Cursor. This is only called on values that are assumed to be specified, that is, they’re not custom and not computed. Therefore this should return a Self reflecting a specified value. If this results in a Parse error then ComputedValue will be checked to see if the parser stopped because it saw a computed value function. If this results in a success, the next token is still checked as it may be a ComputedValue, which - if so - the parsed value will be discarded, and the parser rewound to re-parse this as a ComputedValue.

fn parse_declaration_value(p: &mut Parser<'a>, name: Cursor) -> Result<Self>

impl<'a> Hash for ComponentValues<'a>

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,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for ComponentValues<'a>

fn cmp(&self, other: &ComponentValues<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> Parse<'a> for ComponentValues<'a>

fn parse(p: &mut Parser<'a>) -> Result<Self>

fn try_parse(p: &mut Parser<'a>) -> Result<Self>

impl<'a> PartialEq for ComponentValues<'a>

fn eq(&self, other: &ComponentValues<'a>) -> 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<'a> PartialOrd for ComponentValues<'a>

fn partial_cmp(&self, other: &ComponentValues<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> Peek<'a> for ComponentValues<'a>

fn peek(p: &Parser<'a>, c: Cursor) -> bool

const PEEK_KINDSET: KindSet = KindSet::ANY

impl<'a> Serialize for ComponentValues<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
