Struct SccKey 

pub struct SccKey {
    pub entry: usize,
    pub repeat: usize,
    pub constraint: ConstraintHash,
}

Key for PathEnumerator::scc_paths and PathEnumerator::visited_sccs and PathEnumerator::visited_sccs: which SCC entry block, with what constraint state, and how many additional postfix repeats are allowed.

In scc_paths the constraint field is unused (cache keyed by entry + repeat); in visited_sccs the repeat field is unused (deduplicated by entry + constraint).

Fields

entry: usize

repeat: usize

constraint: ConstraintHash

Trait Implementations

impl Clone for SccKey

fn clone(&self) -> SccKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SccKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for SccKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SccKey

fn eq(&self, other: &SccKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
