Enum QueryResults 

pub enum QueryResults {
    Solutions(QuerySolutionStream),
    Boolean(bool),
    Graph(QueryTripleStream),
}

Results of a SPARQL query.

Variants

Solutions(QuerySolutionStream)

Results of a SELECT query.

Boolean(bool)

Result of a ASK query.

Graph(QueryTripleStream)

Results of a CONSTRUCT or DESCRIBE query.

Implementations

impl QueryResults

pub fn read( reader: impl Read + 'static, format: QueryResultsFormat, ) -> Result<QueryResults, QuerySolutionsToStreamError>

Reads a SPARQL query results serialization.

pub async fn write<W>( self, writer: W, format: QueryResultsFormat, ) -> Result<W, QueryEvaluationError>

where W: Write,

Writes the query results (solutions or boolean).

This method fails if it is called on the Graph results.

pub async fn write_graph<W>( self, writer: W, format: impl Into<RdfFormat>, ) -> Result<W, QueryEvaluationError>

where W: Write,

Writes the graph query results.

This method fails if it is called on the Solution or Boolean results.

Trait Implementations

impl From<QuerySolutionStream> for QueryResults

fn from(value: QuerySolutionStream) -> QueryResults

Converts to this type from the input type.
