I’m excited to get deep into development but have been running into several baffling issues. I understand that the ecosystem is moving fast so it seems prudent to be up to date with the latest development versions. In an attempt to fix https://github.com/holochain/holochain-rust/issues/2028,
I updated to the latest version of hdk. Here is my zome’s Cargo.toml
[package]
name = "cogov"
version = "0.1.0"
authors = ["hc-scaffold-framework"]
edition = "2018"
[dependencies]
futures-io = "=0.3.1"
hdk = "=0.0.42-alpha1"
hdk_proc_macros = "=0.0.42-alpha1"
holochain_json_derive = "=0.0.17"
holochain_persistence_api = "=0.0.11"
holochain_wasm_utils = "=0.0.42-alpha1"
log = "0.4"
serde = "=1.0.89"
serde_json = { version = "=1.0.39", features = ["preserve_order"] }
serde_derive = "=1.0.89"
[lib]
path = "src/lib.rs"
crate-type = ["cdylib"]
When I run hc test I have the following output. Note that I created an issue with futures-io https://github.com/rust-lang/futures-rs/issues/2019
% nix-shell --run "hc test" https://holochain.love :(
