Golang like WaitGroup implementation for sync/async Rust, supportno_std environment.

By default, blocking versionWaitGroup is enabled.

If you are using other async runtime, you need toenbalefuture feature in yourCargo.toml and usewg::AsyncWaitGroup.

• std

  [dependencies]wg ="0.9"

• future

  [dependencies]wg = {version ="0.9",features = ["future"] }

• no_std

  [dependencies]wg = {version ="0.9",default_features =false,features = ["alloc"] }

• no_std & future

  [dependencies]wg = {version ="0.9",default_features =false,features = ["alloc","future"] }

Please seeexamples for details.

• Inspired by Golang sync.WaitGroup andcrossbeam_utils::WaitGroup.
