Function gpx::write

pub fn write<W: Write>(gpx: &Gpx, writer: W) -> Result<(), GpxError>

Writes an activity to GPX format.

Takes any std::io::Write as its writer, and returns a Result<(), GpxError>.

use gpx::write;
use gpx::Gpx;
use gpx::GpxVersion;

let mut data : Gpx = Default::default();
data.version = GpxVersion::Gpx11;

// You can give it anything that implements `std::io::Write`.
write(&data, std::io::stdout()).unwrap();
