Struct satoxid::VarMap[−][src]

pub struct VarMap<V> { /* fields omitted */ }
Expand description

Mapper from user defined variables and integer sat variables.

VarMap is serializable if the serde feature in enabled.

Implementations

impl<V: SatVar> VarMap<V>[src]

pub fn add_var(&mut self, lit: impl Into<VarType<V>>) -> i32[src]

Translates a value of type V to a integer SAT variable used by the backend. If var wasn’t already used it generates a new SAT variable. Depending on whether var is Pos or Neg the returned value is positive or negative.

pub fn get_var(&self, lit: impl Into<VarType<V>>) -> Option<i32>[src]

Same as add_var but it won’t insert new Lit<V> instead returning None.

pub fn lookup(&self, lit: i32) -> Option<Lit<V>>[src]

Lookup the correct V based on the integer SAT variable. Like add_var it keeps the polarity of the input.

impl<V> VarMap<V>[src]

pub fn new_var(&mut self) -> i32[src]

Generates fresh (unused) SAT integer variable.
