RdfDiffEngine

oxirs_core::rdf::diff

Struct RdfDiffEngine

pub struct RdfDiffEngine;

Expand description

Engine for computing and manipulating RDF dataset diffs.

Implementations§

impl RdfDiffEngine

pub fn compute(before: &[Triple], after: &[Triple]) -> DatasetDiff

Compute the diff between before and after triple sets.

added = triples in after that are not in before
removed = triples in before that are not in after

pub fn apply_diff(base: Vec<Triple>, diff: &DatasetDiff) -> Vec<Triple>

Apply diff to base, returning the resulting dataset.

Removes all triples listed in diff.removed from base, then appends all triples in diff.added, de-duplicating the result.

pub fn invert(diff: DatasetDiff) -> DatasetDiff

Invert a diff — swap added and removed so applying the result undoes the original diff.

pub fn compose(d1: DatasetDiff, d2: DatasetDiff) -> DatasetDiff

Compose two diffs into a single diff representing the net effect of applying d1 followed by d2.

Net effect:

Net added = (d1.added ∪ d2.added) \ d2.removed
Net removed = (d1.removed ∪ d2.removed) \ d2.added

pub fn is_empty(diff: &DatasetDiff) -> bool

Return true if diff represents no change (no added and no removed triples).
