NopCloser returns a ReadCloser with a no-op Close method wrapping the provided ReaderCtx.

ReadAll reads from r until an error or EOF and returns the data it read.

ReadCloserAdapter turns an io.ReadCloser into a ReadCloserCtx by ignoring the ctx passed to all the methods.

ReaderAdapter turns an io.Reader into a ReaderCtx by ignoring the ctx passed to Read.

ReaderCtxAdapter turn a ReaderCtx into an io.Reader by capturing a context at construction time and using it for all the Read calls.
