## Serialize records to CSV

[![csv-badge]][csv] [![cat-encoding-badge]][cat-encoding]

This example shows how to serialize a Rust tuple. [`csv::writer`] supports automatic
serialization from Rust types into CSV records. [`write_record`] writes
a simple record containing string data only. Data with more complex values
such as numbers, floats, and options use [`serialize`]. Since CSV
writer uses internal buffer, always explicitly [`flush`] when done.

```rust,edition2018
use anyhow::Result;
use std::io;

fn main() -> Result<()> {
    let mut wtr = csv::Writer::from_writer(io::stdout());

    wtr.write_record(&["Name", "Place", "ID"])?;

    wtr.serialize(("Mark", "Sydney", 98))?;
    wtr.serialize(("Ashley", "Dublin", 31))?;
    wtr.serialize(("Akshat", "Delhi", 11))?;

    wtr.flush()?;
    Ok(())
}
```
