Struct GraphIndexBuilder 

pub struct GraphIndexBuilder { /* private fields */ }

Build a GraphIndex from canonical (s, p, o) integer triples.

Implementations

impl GraphIndexBuilder

pub fn new() -> GraphIndexBuilder

pub fn from_triples(triples: Vec<(u32, u32, u32)>) -> GraphIndexBuilder

Build directly from an owned triple vector — moves it in, avoiding the per-triple push copy when the caller already has the id-triples in a Vec (the assembly path, where they double as the pyramid input).

pub fn with_tile_budget(self, bytes: usize) -> GraphIndexBuilder

Override the per-tile byte budget (tests use tiny budgets to force multi-tile sections on small data).

pub fn with_perms(self, perms: PermSet) -> GraphIndexBuilder

Build only the permutations in perms (default PermSet::ALL). Sections outside the set come out empty and are not written to the file.

pub fn push(&mut self, t: (u32, u32, u32))

pub fn build_seq(self) -> GraphIndex

Build the six permutations one at a time (each permutation’s internal sort still uses every core), so only a single permuted copy of the triples is resident at once instead of all six concurrently. Trades the cross- permutation parallelism of Self::build for a much lower peak RAM — the large-graph low-memory path. Output is byte-identical to Self::build.

pub fn build(self) -> GraphIndex

Trait Implementations

impl Default for GraphIndexBuilder

fn default() -> GraphIndexBuilder

Returns the “default value” for a type.
