Getting base16ct error #85

Closed mikedotexe closed 2 years ago

mikedotexe commented 2 years ago

I am not sure if this is my Rust setup, but I am consistently trying to run:

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/rust-optimizer:0.12.3 ./contracts/*/

in the cw-contracts repo and getting:

error: failed to download `base16ct v0.1.1`

Caused by:
  unable to get packages from source

Caused by:
  failed to parse manifest at `/usr/local/cargo/registry/src/github.com-1ecc6299db9ec823/base16ct-0.1.1/Cargo.toml`

Caused by:
  feature `edition2021` is required

  The package requires the Cargo feature called `edition2021`, but that feature is not stabilized in this version of Cargo (1.55.0 (32da73ab1 2021-08-23)).

and indeed, I see the manifest has this: https://github.com/RustCrypto/formats/blame/7cadd9d3696b6ec06b79281e08805625dd8f3187/base64ct/Cargo.toml#L16

edition = "2021"

but that's been there for 10 months, so maybe that's not as new as I'd think.

Anyway, writing this issue but again, not positive if it's my setup.

Or maybe we just need to update the cargo version

cosmwasm/rust-optimizer ships a version of Rust. The Rust version in 0.12.3 is too low to support Rust edition2021. You can just upgrade to the latest version 0.12.6. See https://github.com/CosmWasm/rust-optimizer/blob/main/CHANGELOG.md

Closing as this is fixed in more recent versions of rust-optimizer/workspace-optimizer which ship more recent Rust versions. If you run into trouble with the latest version, please open a new ticket. Thanks!
