Function unnest_ndjson::unnest_to_ndjson

source · [−]

pub fn unnest_to_ndjson<R: Read>(
    from: R,
    to: impl Sinker,
    target: usize,
    header_style: HeaderStyle
) -> Result<()>

Expand description

Consume a large JSON document from a Read, and write sub documents to a destination.

The typical destination is just a Write implementation, like a std::fs::File, or a Vec. Alternatively, you can use the Sinker interface to get access to fragments of documents.

Configure the level of un-nesting with the target parameter. 1 will remove one level of nesting, such as converting [{"a":5}, {"a":6}] into {"a":5} and {"a":6}.

header_style controls how much context to retain. See HeaderStyle.
