Rust contract fails to run tests on clean run

[ilblackdragon]

My rust setup:

$ cargo --version
cargo 1.87.0 (99624be96 2025-05-06)
$ rustup --version
rustup 1.28.2 (e4f3ad6f8 2025-04-28)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.87.0 (17067e9ac 2025-05-09)`

Next commands :

git clone https://github.com/near-examples/counters.git
cd counters/contract-rs
cargo test

...

failures:
    test_can_be_decremented
    test_can_be_decremented_with_points
    test_can_be_incremented
    test_can_be_incremented_with_points
    test_can_be_reset

Thanks for catching it. Unfortunately, nearcore does not support Rust 1.87+ due to the new wasm features enabled by default that cannot be opted out.

Please, update the rust-toolchain.yaml file to use 1.86 instead of "stable"

counters/contract-rs/rust-toolchain.toml

Line 2 in 81d837a

channel = "stable"

We had a few announcements, and I have just posted another reminder: https://t.me/NEARDevHub/461
