Struct ShowRule 

pub struct ShowRule<'a>(/* private fields */);

A show rule: show heading: it => emph(it.body).

Implementations

impl<'a> ShowRule<'a>

pub fn selector(self) -> Option<Expr<'a>>

Defines which nodes the show rule applies to.

pub fn transform(self) -> Expr<'a>

The transformation recipe.

Trait Implementations

impl<'a> AstNode<'a> for ShowRule<'a>

fn from_untyped(node: &'a SyntaxNode) -> Option<Self>

Convert a node into its typed variant.

fn to_untyped(self) -> &'a SyntaxNode

A reference to the underlying syntax node.

fn placeholder() -> Self

A placeholder for this node type. If the underlying CST has syntax errors or did not come from the parser, the AST is not guaranteed to be valid. But instead of panicking in that case, we return placeholder nodes.

fn span(self) -> Span

The source code location.

impl<'a> Clone for ShowRule<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for ShowRule<'a>

impl<'a> Debug for ShowRule<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for ShowRule<'a>

impl<'a> Hash for ShowRule<'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> PartialEq for ShowRule<'a>

fn eq(&self, other: &ShowRule<'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.
