Rust smart contract library designed for Dharitri's VM. Also provides a debugging mode with mocks.
For examples on how to use the Dharitri WASM framework, see https://github.com/DharitriNetwork/dharitri-wasm-rs/tree/master/contracts/examples
The framework is designed to be easiest to use with the Dharitri IDE VSCode extension: https://marketplace.visualstudio.com/items?itemName=Dharitri.vscode-dharitri-ide
To build a smart contract without the IDE, run the following command in the contract crate:
./build-wasm.sh
In case this doesn't work, you might not have rustc configured properly. Try:
rustup toolchain install nightly
rustup default nightly
rustup target add wasm32-unknown-unknown
Step-by-step debugging of smart contracts is possible in VSCode. To do this, it is required to have a separate debug crate and to have tasks.json and launch.json in .vscode properly configured. See https://github.com/DharitriNetwork/dharitri-wasm-rs/tree/master/contracts/examples for examples on how to set this up.
To debug macros:
cargo +nightly rustc --bin wasm -- -Z unstable-options --pretty=expanded > demacroed.rs
To check wasm size:
twiggy top -n 20 target/wasm32-unknown-unknown/release/wasm.wasm
