У меня странная проблема с зависимостями. Вот шаги для воспроизведения:
❯ rustc -V
rustc 1.35.0-nightly (82e2f3ec2 2019-03-20)
❯ git clone https://github.com/google/tarpc.git
❯ cd tarpc/example-service
❯ cargo build
Finished dev [unoptimized + debuginfo] target(s) in 0.13s
❯ git rev-parse HEAD
06544faa5a0872d4be989451afc0a2b1e1278df4
Теперь я заменяю строку в Cargo.toml с
bincode-transport = { package = "tarpc-bincode-transport", version = "0.3", path = "../bincode-transport" }
до
bincode-transport = { package = "tarpc-bincode-transport", git="https://github.com/google/tarpc.git", rev="06544faa5a0872d4be989451afc0a2b1e1278df4" }
, представляющий ту же кодовую базу (я думаю, version = 0.3
не имеет смысла),
Тогда у меня ошибка сборки
❯ cargo build

cargo clean
не помогло. Как это возможно?
