[][src]Struct gf::ai::state::VarState

pub struct VarState<T: Clone + Eq> { /* fields omitted */ }

🟢 Map-like structure for maintaining abstract state of variables.

Internally, this is a thin adapter over a HashLattice where keys are Vars.


impl<T: Clone + Eq> VarState<T>[src]

pub fn clear(&mut self)[src]

Clear variable state to all default (⊥ or ⊤) values.

pub fn get(&self, var: Var) -> &T[src]

Return variable state.

pub fn get_vec(&self, vars: &[Var]) -> Vec<T>[src]

Return a vector of cloned variable states.

pub fn take(&mut self, var: Var) -> T[src]

Return variable state leaving the default (⊥ or ⊤) value in its place.

pub fn set(&mut self, var: Var, state: T)[src]

Set variable state.

pub fn copy(&mut self, source_var: Var, target_var: Var)[src]

Copy state from source_var to target_var.

pub fn edge<D: Direction>(&mut self, edge: Edge<'_>)[src]

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<'_, Call>) -> Self[src]

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<'_, 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<'_, Mix>)[src]

Propagate state across a MIX statement.

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