Struct Closure 

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

A closure: (x, y) => z.

Implementations

impl<'a> Closure<'a>

pub fn name(self) -> Option<Ident<'a>>

The name of the closure.

This only exists if you use the function syntax sugar: let f(x) = y.

pub fn params(self) -> Params<'a>

The parameter bindings.

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

The body of the closure.

Trait Implementations

impl<'a> AstNode<'a> for Closure<'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 Closure<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Closure<'a>

impl<'a> Debug for Closure<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for Closure<'a>

impl<'a> Hash for Closure<'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 Closure<'a>

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