Struct CallEdge 

pub struct CallEdge {
    pub caller: FuncId,
    pub callee: FuncId,
    pub range: SourceRange,
}

One direct call, from the function whose body holds it to the function it names.

Sema records these as it checks the calls, and check_safe is the one thing that reads them: a safe function calling one that is not gets a diagnostic worded in C rather than rustc’s “call to unsafe function”. A call through a pointer has no edge — there is no callee to name — and is left to rustc, which refuses it in a safe function like any other unsafe operation.

Fields

caller: FuncId

The function the call was written in.

callee: FuncId

The function it calls.

range: SourceRange

Where the callee was named, which is where a diagnostic points.
