# Overview
`rw_cell` provides the ability to securely write data from one location of application and read it from another
even if Writer and Reader located in different threads without copying/cloning and blocking access to data.
# MWSR fun example
```rust
fn main() {
let (w0, mut r) = rw_cell::mwsr::cell(vec!["Ukraine"; 1000]);
let w1 = r.get_writer();
let w2 = r.get_writer();
let w3 = r.get_writer();
let w4 = r.get_writer();
let w5 = r.get_writer();
std::thread::spawn(move || loop {
w0.write(vec!["Slovakia"; 1001])
});
std::thread::spawn(move || loop {
w1.write(vec!["Estonia"; 1002])
});
std::thread::spawn(move || loop {
w2.write(vec!["Czechia"; 1003])
});
std::thread::spawn(move || loop {
w3.write(vec!["United Kingdom"; 1004])
});
std::thread::spawn(move || loop {
w4.write(vec!["Lithuania"; 1005])
});
std::thread::spawn(move || loop {
w5.write(vec!["Latvia"; 1006])
});
