[−][src]Struct tokio::io::Stdin
This is supported on
feature="io-std"
only.A handle to the standard input stream of a process.
The handle implements the AsyncRead
trait, but beware that concurrent
reads of Stdin
must be executed with care.
As an additional caveat, reading from the handle may block the calling future indefinitely, if there is not enough data available. This makes this handle unsuitable for use in any circumstance where immediate reaction to available data is required, e.g. interactive use or when implementing a subprocess driven by requests on the standard input.
Created by the stdin
function.
