Struct DeclarationList 

pub struct DeclarationList<'a, V, M>
where
    V: DeclarationValue<'a, M>,
    M: NodeMetadata,
{
    pub open_curly: LeftCurly,
    pub declarations: Vec<'a, Declaration<'a, V, M>>,
    pub close_curly: Option<RightCurly>,
    /* private fields */
}

A generic struct that can be used for AST nodes representing a rule’s block, that is only capable of having child declarations.

It is an implementation of “declaration-list”. It includes an error tolerance in that the ending } token can be omitted, if at the end of the file.

The <V> must implement the DeclarationValue trait, as it is passed to Declaration.

Trait Implementations

impl<'a, V, M> Clone for DeclarationList<'a, V, M>

where V: DeclarationValue<'a, M> + Clone, M: NodeMetadata + Clone,

fn clone(&self) -> DeclarationList<'a, V, M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, V, M> Debug for DeclarationList<'a, V, M>

where V: DeclarationValue<'a, M> + Debug, M: NodeMetadata + Debug,

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

Formats the value using the given formatter.

impl<'a, V, M> Hash for DeclarationList<'a, V, M>

where V: DeclarationValue<'a, M> + Hash, M: NodeMetadata + Hash,

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, V, M> NodeWithMetadata<M> for DeclarationList<'a, V, M>

where V: DeclarationValue<'a, M>, M: NodeMetadata,

fn metadata(&self) -> M

Returns the complete aggregated metadata for this node (self + children)

fn self_metadata(&self, initial: M) -> M

Returns the metadata contributed by this node itself plus and child meta. Most nodes don’t contribute metadata, so can simply return child. Other nodes may want to alter the metadata; supplying their own modifications to initial.

impl<'a, V, M> Ord for DeclarationList<'a, V, M>

where V: DeclarationValue<'a, M> + Ord, M: NodeMetadata + Ord,

fn cmp(&self, other: &DeclarationList<'a, V, M>) -> 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, V, M> Parse<'a> for DeclarationList<'a, V, M>

where V: DeclarationValue<'a, M>, M: NodeMetadata,

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

where Iter: Iterator<Item = Cursor> + Clone,

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

where I: Iterator<Item = Cursor> + Clone,

impl<'a, V, M> PartialEq for DeclarationList<'a, V, M>

where V: DeclarationValue<'a, M> + PartialEq, M: NodeMetadata + PartialEq,

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

where V: DeclarationValue<'a, M> + PartialOrd, M: NodeMetadata + PartialOrd,

fn partial_cmp(&self, other: &DeclarationList<'a, V, M>) -> 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, V, M> Peek<'a> for DeclarationList<'a, V, M>

where V: DeclarationValue<'a, M>, M: NodeMetadata,

const PEEK_KINDSET: KindSet

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