Struct gf::ai::state::State

pub struct State<'a, A, V, S> where
    V: Bottom + Clone + Eq,
    S: Clone + SpaceState<A, V>,  {
    pub var_state: VarState<V>,
    pub space_state: SpaceStateMap<'a, A, V, S>,
}

🟢 Common implementation of an abstract state composed of a VarState and a SpaceStateMap.

Addresses are represented as A and values as V. Space state is provided by S.

Fields

var_state: VarState<V>

Variable state.

space_state: SpaceStateMap<'a, A, V, S>

Space state.

Implementations

impl<'a, A, V, S> State<'a, A, V, S> where
    V: Bottom + Clone + Eq,
    S: Clone + SpaceState<A, V>, 

pub fn edge<D: Direction>(&mut self, edge: Edge<'a>)

Propagate state across an intraprocedural edge.

This method is a drop-in implementation for Interp::edge, or a part thereof.

pub fn call<D: Direction>(&self, stmt: Stmt<'a, Call>) -> Self

Propagate state across a CALL statement.

This method is a drop-in implementation for Interp::call.

pub fn call_ret<D: Direction>(
    &mut self,
    callee_state: Self,
    stmt: Stmt<'a, Call>
)

Propagate state across a return from a CALL statement.

This method is a drop-in implementation for Interp::call_ret.

pub fn mix<D: Direction>(&mut self, stmt: Stmt<'a, Mix>)

Propagate state across a MIX statement.

This method is a drop-in implementation for Interp::mix.
