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<&'hir FnDecl<'hir>>

pub fn fn_sig(self) -> Option<&'hir FnSig<'hir>>

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

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

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

pub fn fn_kind(self) -> Option<FnKind<'hir>>

pub fn tuple_fields(&self) -> Option<&'hir [FieldDef<'hir>]>

Get the fields for the tuple-constructor, if this node is a tuple constructor, otherwise None

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>

Converts this type into the (usually inferred) input type.

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.
