Struct FromTokioAsyncReadJsonReader

pub struct FromTokioAsyncReadJsonReader<R: AsyncRead + Unpin> { /* private fields */ }

Available on crate feature async-tokio only.

Expand description

Parses a JSON file from an AsyncRead implementation.

use json_event_parser::{FromTokioAsyncReadJsonReader, JsonEvent};

let mut reader = FromTokioAsyncReadJsonReader::new(b"{\"foo\": 1}".as_slice());
assert_eq!(reader.read_next_event().await?, JsonEvent::StartObject);
assert_eq!(reader.read_next_event().await?, JsonEvent::ObjectKey("foo".into()));
assert_eq!(reader.read_next_event().await?, JsonEvent::Number("1".into()));
assert_eq!(reader.read_next_event().await?, JsonEvent::EndObject);
assert_eq!(reader.read_next_event().await?, JsonEvent::Eof);
