body: Box<Expr>

Trait Implementations

impl Clone for Closure

fn clone(&self) -> Closure

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Closure

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

Formats the value using the given formatter.

impl Display for Closure

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

Formats the value using the given formatter.

impl From<Closure> for ExprKind

fn from(value: Closure) -> Self

Converts to this type from the input type.

impl Hash for Closure

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 Closure

fn eq(&self, other: &Closure) -> 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 Walk for Closure

fn visit_in<'a, V: Visit<'a>>(&'a self, v: &mut V)

Calls the respective visit_* function in V

fn children<'a, V: Visit<'a>>(&'a self, v: &mut V)

Walks the children of self, visiting them in V

impl WeightOf for Closure

fn weight_of(&self) -> usize

Approximates the size of a syntax tree without including pointer/indirection or padding.

impl Eq for Closure

impl StructuralPartialEq for Closure
