Function robust_arduino_serial::write_i32

pub fn write_i32<T: Write>(file: &mut T, num: i32) -> Result<usize>

Write four bytes int to a file/serial port. It returns the number of bytes written

Example

use std::io::Cursor;
use robust_arduino_serial::*;

let mut buffer = Cursor::new(Vec::new());
let big_number: i32 = -16384; // -2^14

// write 32 bits (four bytes) to the buffer
write_i32(&mut buffer, big_number).unwrap();
