Struct Attribute 

pub struct Attribute { /* private fields */ }

A Attribute node (family.ungram rule Attribute).

Implementations

impl Attribute

pub fn key(&self) -> Option<Name>

pub fn value(&self) -> Option<AttrValue>

pub fn expr(&self) -> Option<Expr>

pub fn dot_token(&self) -> Option<SyntaxToken>

pub fn eq_token(&self) -> Option<SyntaxToken>

pub fn require_token(&self) -> Option<SyntaxToken>

pub fn ensure_token(&self) -> Option<SyntaxToken>

impl Attribute

pub fn key_segments(&self) -> AstChildren<Name>

The key’s name segments in source order: one for a family key (labels), two for an rsdl backend key (linux.cpuset, rsdl reference §5). Empty for a predicate attribute, and for a key the parser held in an ErrorNode (a reserved word, FORM-105).

pub fn predicate_kind(&self) -> Option<PredicateKind>

The predicate keyword of a require/ensure attribute; None for the flag and assignment forms.

Trait Implementations

impl AstNode for Attribute

fn cast(syntax: SyntaxNode) -> Option<Self>

fn syntax(&self) -> &SyntaxNode

The underlying untyped node.

impl Clone for Attribute

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attribute

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

Formats the value using the given formatter.

impl Eq for Attribute

impl Hash for Attribute

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 PartialEq for Attribute

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

Equality operator ==.

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