for managing IC projects
If you are looking for a crate to communicate with existing canisters on IC, you may want to check agent-rs.
A canister
is a WebAssembly (wasm) module that can run on the Internet Computer.
To be a canister
, a wasm module should communicate with the execution environment using Canister interfaces (System API).
This repo provides libraries and tools to facilitate developing canisters in Rust.
ic-cdk
: Bindings of the System API.ic-cdk-macros
: Annotate functions with attribute macros to make them exposed public interfaces.ic-cdk-timers
: The library implements multiple and periodic timers.ic-certified-map
: An implementation of map which support certified queries.ic-ledger-types
: Type definitions to communicate with the ICP ledger canister.
In Cargo.toml:
[lib]
crate-type = ["cdylib"]
[dependencies]
candid = "0.8.0" # this is required if you want to use the `#[import]` macro
ic-cdk = "0.6"
Then in your rust source code:
#[ic_cdk::query]
fn print() {
ic_cdk::print("Hello World from DFINITY!");
}
