Use Cargo Odra to generate, build and test you code.
use odra::prelude::*;
use odra::Var;
#[odra::module]
pub struct Flipper {
value: Var<bool>,
}
#[odra::module]
impl Flipper {
pub fn init(&mut self) {
self.value.set(false);
}
pub fn set(&mut self, value: bool) {
self.value.set(value);
}
pub fn flip(&mut self) {
self.value.set(!self.get());
}
pub fn get(&self) -> bool {
self.value.get_or_default()
}
}
#[cfg(test)]
mod tests {
use crate::flipper::FlipperHostRef;
use odra::host::{Deployer, NoArgs};
#[test]
fn flipping() {
let env = odra_test::env();
let mut contract = FlipperHostRef::deploy(&env, NoArgs);
assert!(!contract.get());
contract.flip();
assert!(contract.get());
}
}
Checkout our examples. It shows most of Odra features.
