[−][src]Struct varisat_checker::clauses::Clauses

pub struct Clauses {
    pub next_clause_id: u64,
    pub literal_buffer: Vec<Lit>,
    garbage_size: usize,
    pub clauses: HashMap<ClauseHash, SmallVec<[Clause; 1]>>,
    pub unit_clauses: Vec<Option<UnitClause>>,
    pub unit_conflict: Option<[u64; 2]>,
}

Checker clause storage.

Fields

next_clause_id: u64

Next clause id to use.

literal_buffer: Vec<Lit>

Literal storage for clauses,

garbage_size: usize

Number of literals in the buffer which are from deleted clauses.

clauses: HashMap<ClauseHash, SmallVec<[Clause; 1]>>

Stores all known non-unit clauses indexed by their hash.

unit_clauses: Vec<Option<UnitClause>>

Stores known unit clauses and propagations during a clause check.

unit_conflict: Option<[u64; 2]>

This stores a conflict of input unit clauses.

Our representation for unit clauses doesn't support conflicting units so this is used as a workaround.

Methods

impl Clauses[src]

pub fn lit_value(&self, lit: Lit) -> Option<(bool, UnitClause)>[src]

Value of a literal if known from unit clauses.
