Struct SccData

source 
struct SccData<S: Idx, A: Annotation> {
    scc_details: IndexVec<S, SccDetails<A>>,
    all_successors: Vec<S>,
}

Fields§

§scc_details: IndexVec<S, SccDetails<A>>

Maps SCC indices to their metadata, including offsets into all_successors.

§all_successors: Vec<S>

Contains the successors for all the Sccs, concatenated. The range of indices corresponding to a given SCC is found in its scc_details.range.

Implementations§

source§

impl<S: Idx, A: Annotation> SccData<S, A>

source

fn len(&self) -> usize

Number of SCCs,

source

fn successors(&self, scc: S) -> &[S]

Returns the successors of the given SCC.

source

fn create_scc( &mut self, successors: impl IntoIterator<Item = S>, annotation: A, ) -> S

Creates a new SCC with successors as its successors and the maximum weight of its internal nodes scc_max_weight and returns the resulting index.

source

fn annotation(&self, scc: S) -> A
