pub fn run(argv: impl IntoIterator<Item = String>) -> Result<(), String>Expand description
Dispatch one command from an argv-style iterator (the program name is
consumed and ignored). Shared by the nichlink and cargo-nichlink
binaries, and writes its reports to process stdout.
从 argv 风格的迭代器分发一条命令（程序名会被消耗忽略）。nichlink 与
cargo-nichlink 两个二进制共用，报告写到进程 stdout。
