Reduce memory usage during Rust compilation

[leoadonia]

ld might be OOM killed during ten_manager compilation, the memory usage might be over 2Gi.

Possible actions:

• Using lld instead.
• Split the crate dependencies into small projects.

临时解决方法, 增加 swap 大小:

• 查看 swap file:

  swapon --show

• 如果存在, 且不满足大小要求, 可以先关闭, 重新创建:

  swapoff /swapfile

• 创建大小为 4G 的 swap:

  fallocate -l 4G /swapfile
  chmod 600 /swapfile
  
  # 格式化
  mkswap /swapfile

• 启用:

  swapon /swapfile

• 挂载

  在 /etc/fstab 中增加如下内容:

  /swapfile   none   swap   sw   0   0
