incremental-writer 0.1.2

# incremental-writer


incremental-writer is a library which provides writers to write in different formats to files on disk, currently 
only JSON is supported. incremental_writer::json::IncrementalJsonWriter provides a writer that takes a File writer
and incrementally writes JSON objects to an array inside that file using serde_json. 

Works on both Windows and Unix.

It implements the write trait's write(&[u8]) and flush() as well as write_json() which takes
any serialisable object and writes it to the underlying array.

example: 
    
    extern crate incremental_writer;
    use incremental_writer::json;
    use serde::{Serialize, Deserialize};
        fn main() {
        let rows: Vec<Record> = vec![0, 1, 2, 3, 4, 5, 6, 7 , 8, 9, 10]
            .iter()
            .map(|num| Record { name: String::from("Test"), detail: *num})
            .collect();
            let out = std::fs::File::create("test.json").unwrap();
            let mut writer = json::IncrementalJsonWriter::new(out);
        for row in rows {
            //the element is written to the file on each iteration
            //if it stops before finishing, the JSON is still valid
            writer.write_json(&row).unwrap();
        }
    }
    #[derive(Serialize, Deserialize, Debug)]
    struct Record { 
        name: String,
        detail: u32
    }
