Trait Query 

pub trait Query: Sized {
    type Error: Error + Send + Sync + 'static;

    // Required methods
    fn parse(query_source: &str) -> Result<Self, Self::Error>;
    fn parse_with(
        query_source: &str,
        base: Iri<&str>,
    ) -> Result<Self, Self::Error>;
}

Preprocessed query, ready for execution.

This trait exist to allow some implementations of SparqlDataset to mutualize the parsing of queries in the prepare_query method.

Required Associated Types

type Error: Error + Send + Sync + 'static

The error type that might be raised when parsing a query.

Required Methods

fn parse(query_source: &str) -> Result<Self, Self::Error>

Parse the given text into a Query.

fn parse_with(query_source: &str, base: Iri<&str>) -> Result<Self, Self::Error>

Parse the given text into a Query, using the given base IRI

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
