Function with_deserializer_from_reader 

pub fn with_deserializer_from_reader<R, Out, F>(
    reader: R,
    f: F,
) -> Result<Out, Error>
where
    for<'de, 'e> F: FnOnce(Deserializer<'de, 'e>) -> Result<Out, Error>,
    R: Read,

Create a streaming crate::Deserializer for any std::io::Read and run a closure against it.

This is the reader-based counterpart to with_deserializer_from_str. It consumes a byte-oriented reader and streams events into the deserializer. The reader accepts BOM-marked UTF-8, UTF-16LE, and UTF-16BE. If no recognized BOM is present, the input bytes are treated as UTF-8.
