Enum Node 

pub enum Node<'tcx> {
    Analyzed {
        call_sites: Vec<CallSite<'tcx>>,
    },
    ExternalCrate,
    Leaf(DefKind),
}

A node in the call graph. The node’s provenance (source item vs monomorphization) is carried by its NodeKey; the node itself only records, when it has an analyzable body, the call sites observed in it.

Variants

Analyzed

MIR was available and walked. call_sites are the Call/Assert terminators observed.

Fields

call_sites: Vec<CallSite<'tcx>>

ExternalCrate

External crate function — panic spec looked up from crate metadata.

Leaf(DefKind)

Function with no analyzable body (no Rust body by design, MIR unavailable, or a non-Item instance such as a shim or virtual dispatch stub). Conservatively treated as MightPanic.

Implementations

impl<'tcx> Node<'tcx>

fn call_sites(&self) -> &[CallSite<'tcx>]

Call sites observed in this node’s body. Empty for non-Analyzed nodes.

pub fn resolved_callees(&self) -> impl Iterator<Item = NodeKey<'tcx>>

The callee nodes of this node’s resolved call sites (skipping unresolved/dynamic ones).

Trait Implementations

impl<'tcx> Clone for Node<'tcx>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for Node<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> Display for Node<'tcx>

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

Formats the value using the given formatter.
