Usage

Use Cargo Odra to generate, build and test you code.

Example

use odra::Variable;

#[odra::module]
pub struct Flipper {
    value: Variable<bool>,
}

#[odra::module]
impl Flipper {
    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 super::FlipperDeployer;

    #[test]
    fn flipping() {
        let mut contract = FlipperDeployer::default();
        assert_eq!(contract.get(), false);
        contract.flip();
        assert_eq!(contract.get(), true);
    }
}

Backends

Odra is designed to integrate with most WebAssembly-based smart contract systems.

Integrated blockchains:

• Casper Network.

Tests

Before running tests make sure you have following packages installed:

• Rust toolchain (see rustup.rs) with wasm32-unknown-unknown target.
• wasm-strip (see wabt)
• cargo-odra (see Cargo Odra)
• just (see just)

Run tests:

$ just test
