Struct Store 

pub struct Store { /* private fields */ }

Oxigraph-compatible store implementation

This provides the same API as oxigraph::Store for compatibility

Uses interior mutability to match Oxigraph’s API where mutations take &self

Implementations

impl Store

pub fn new() -> Result<Self>

Creates a new in-memory store

This matches oxigraph::Store::new()

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self>

Opens a persistent store at the given path

This matches oxigraph::Store::open()

pub fn insert<'a>(&self, quad: impl Into<QuadRef<'a>>) -> Result<bool>

Inserts a quad into the store

Returns true if the quad was not already present

pub fn extend<'a>( &self, quads: impl IntoIterator<Item = impl Into<QuadRef<'a>>>, ) -> Result<()>

Extends the store with an iterator of quads

pub fn remove<'a>(&self, quad: impl Into<QuadRef<'a>>) -> Result<bool>

Removes a quad from the store

Returns true if the quad was present

pub fn load_from_reader<R: BufRead>( &self, reader: R, format: RdfFormat, base_iri: Option<&str>, graph: Option<impl Into<GraphName>>, ) -> Result<()>

Loads a file into the store

pub fn dump_to_writer<'a, W: Write>( &self, writer: W, format: RdfFormat, graph: Option<impl Into<GraphNameRef<'a>>>, ) -> Result<()>

Dumps the store content to a writer

pub fn contains<'a>(&self, quad: impl Into<QuadRef<'a>>) -> Result<bool>

Checks if the store contains a given quad

pub fn len(&self) -> Result<usize>

Returns the number of quads in the store

pub fn is_empty(&self) -> Result<bool>

Checks if the store is empty

pub fn quads_for_pattern<'a>( &self, subject: Option<impl Into<SubjectRef<'a>>>, predicate: Option<impl Into<PredicateRef<'a>>>, object: Option<impl Into<ObjectRef<'a>>>, graph_name: Option<impl Into<GraphNameRef<'a>>>, ) -> QuadIter

Returns an iterator over all quads matching a pattern

pub fn iter(&self) -> QuadIter

Returns an iterator over all quads in the store

pub fn named_graphs(&self) -> GraphNameIter

Returns all named graphs in the store

pub fn contains_named_graph<'a>( &self, graph_name: impl Into<NamedOrBlankNodeRef<'a>>, ) -> Result<bool>

Checks if the store contains a given named graph

pub fn clear(&self) -> Result<()>

Clears the store

pub fn clear_graph<'a>( &self, graph_name: impl Into<GraphNameRef<'a>>, ) -> Result<()>

Clears a specific graph

pub fn query(&self, query: &str) -> Result<QueryResults>

Executes a SPARQL query

pub fn update(&self, update_str: &str) -> Result<()>

Executes a SPARQL update

pub fn transaction<T, E>( &self, f: impl FnOnce(&mut AcidTransaction) -> Result<T, E>, ) -> Result<T, E>

where E: From<OxirsError>,

Creates a transaction for the store

This method provides ACID transaction support with automatic commit/abort handling. The transaction uses Snapshot isolation level by default.

Example

store.transaction(|tx| {
    // Perform transactional operations
    Ok(())
})?;

pub fn validate(&self) -> Result<()>

Validates the store integrity

pub fn optimize(&self) -> Result<()>

Optimizes the store layout

pub fn backup<P: AsRef<Path>>(&self, path: P) -> Result<()>

Backs up the store to a path

pub fn flush(&self) -> Result<()>

Flushes any pending changes to disk

Trait Implementations

impl Default for Store

fn default() -> Self

Returns the “default value” for a type.
