Struct TokioAsyncWriterJsonLdSerializer 

pub struct TokioAsyncWriterJsonLdSerializer<W: AsyncWrite + Unpin> { /* private fields */ }

Available on crate feature async-tokio only.

Serializes a JSON-LD file to a AsyncWrite implementation.

Can be built using JsonLdSerializer::for_tokio_async_writer.

use oxrdf::{NamedNodeRef, QuadRef, LiteralRef, GraphNameRef};
use oxrdf::vocab::rdf;
use oxjsonld::JsonLdSerializer;

let mut serializer = JsonLdSerializer::new().with_prefix("schema", "http://schema.org/")?.for_tokio_async_writer(Vec::new());
serializer.serialize_quad(QuadRef::new(
    NamedNodeRef::new("http://example.com#me")?,
    rdf::TYPE,
    NamedNodeRef::new("http://schema.org/Person")?,
    GraphNameRef::DefaultGraph
)).await?;
serializer.serialize_quad(QuadRef::new(
    NamedNodeRef::new("http://example.com#me")?,
    NamedNodeRef::new("http://schema.org/name")?,
    LiteralRef::new_language_tagged_literal_unchecked("Foo Bar", "en"),
    GraphNameRef::DefaultGraph
)).await?;
assert_eq!(
    b"{\"@context\":{\"schema\":\"http://schema.org/\"},\"@graph\":[{\"@id\":\"http://example.com#me\",\"http://www.w3.org/1999/02/22-rdf-syntax-ns#type\":[{\"@id\":\"http://schema.org/Person\"}],\"http://schema.org/name\":[{\"@language\":\"en\",\"@value\":\"Foo Bar\"}]}]}",
    serializer.finish().await?.as_slice()
);

Implementations

impl<W: AsyncWrite + Unpin> TokioAsyncWriterJsonLdSerializer<W>

pub async fn serialize_quad<'a>( &mut self, t: impl Into<QuadRef<'a>>, ) -> Result<()>

Serializes an extra quad.

pub async fn finish(self) -> Result<W>

Ends the write process and returns the underlying Write.
