Struct tokio_process::ChildStdout [−][src]
pub struct ChildStdout { /* fields omitted */ }The standard output stream for spawned children.
This type implements the Read trait to read data from the stdout handle
of a child process. Note that this type is also “futures aware” meaning
that it is both (a) nonblocking and (b) will panic if used off of a
future’s task.
