Module pipe

Virtual pipes.

These types provide easy implementations of WasiFile that mimic much of the behavior of Unix pipes. These are particularly helpful for redirecting WASI stdio handles to destinations other than OS files.

Some convenience constructors are included for common backing types like Vec<u8> and String, but the virtual pipes can be instantiated with any Read or Write type.

Structs

• AsyncReadStream
  Provides a HostInputStream impl from a [tokio::io::AsyncRead] impl
• AsyncWriteStream
  Provides a HostOutputStream impl from a [tokio::io::AsyncWrite] impl
• ClosedInputStream
  A stream that is ready immediately, but will always report that it’s closed.
• ClosedOutputStream
  An output stream that is always closed.
• MemoryInputPipe
• MemoryOutputPipe
• SinkOutputStream
  An output stream that consumes all input written to it, and is always ready.
