Struct CallGraphInfo 

pub struct CallGraphInfo { /* private fields */ }

Module-level internal-call graph facts.

Implementations

impl CallGraphInfo

pub fn new(module: &Module) -> CallGraphInfo

Computes call graph facts for module.

pub fn callees( &self, func: FunctionId, ) -> Option<&HashSet<FunctionId, FxBuildHasher>>

Returns functions directly called by func.

pub fn callers( &self, func: FunctionId, ) -> Option<&HashSet<FunctionId, FxBuildHasher>>

Returns functions that directly call func.

pub fn entry_functions(&self) -> &HashSet<FunctionId, FxBuildHasher>

Returns entry functions: external ABI entries, constructor, fallback, and receive.

pub fn reachable_from_entries(&self) -> &HashSet<FunctionId, FxBuildHasher>

Returns all functions reachable from entry functions.

pub fn is_recursive(&self, func: FunctionId) -> bool

Returns true if func is directly or indirectly recursive.

pub fn reachable_bodies_from( &self, roots: impl IntoIterator<Item = FunctionId>, ) -> HashSet<FunctionId, FxBuildHasher>

Returns functions reachable from roots that have MIR bodies.

pub fn reachable_from_roots( &self, roots: impl IntoIterator<Item = FunctionId>, ) -> HashSet<FunctionId, FxBuildHasher>

Returns all functions reachable from roots.
