Implementations

impl<'hir> Node<'hir>

pub fn ident(&self) -> Option<Ident>

Get the identifier of this Node, if applicable.

Edge cases

Calling .ident() on a Node::Ctor will return None because Ctors do not have identifiers themselves. Instead, call .ident() on the parent struct/variant, like so:

ctor
    .ctor_hir_id()
    .and_then(|ctor_id| tcx.hir().find(tcx.hir().get_parent_node(ctor_id)))
    .and_then(|parent| parent.ident())

pub fn fn_decl(&self) -> Option<&FnDecl<'hir>>

pub fn body_id(&self) -> Option<BodyId>

pub fn generics(&self) -> Option<&'hir Generics<'hir>>

pub fn hir_id(&self) -> Option<HirId>

pub fn constness_for_typeck(&self) -> Constness

Returns Constness::Const when this node is a const fn/impl/item.

pub fn as_owner(self) -> Option<OwnerNode<'hir>>

Trait Implementations

impl<'hir> Clone for Node<'hir>

fn clone(&self) -> Node<'hir>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'hir> Debug for Node<'hir>

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

Formats the value using the given formatter.

impl<'hir, __CTX> HashStable<__CTX> for Node<'hir> where
    __CTX: HashStableContext, 

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl<'hir> Into<Node<'hir>> for OwnerNode<'hir>

fn into(self) -> Node<'hir>

Performs the conversion.

impl<'hir> Copy for Node<'hir>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
