Struct io_streams::StreamDuplexer [−][src]
pub struct StreamDuplexer { /* fields omitted */ }
Expand description
An unbuffered and unlocked interactive combination input and output stream,
implementing Read
and Write
.
This may hold two file descriptors, one for reading and one for writing, such as stdin and stdout, or it may hold one file handle for both reading and writing, such as for a TCP socket.
There is no file
constructor, even though File
implements both Read
and Write
, because normal files are not interactive. However, there is a
char_device
constructor for character device files.
Implementations
impl StreamDuplexer
[src]
impl StreamDuplexer
[src]pub fn stdin_stdout() -> Result<Self>
[src]
pub fn stdin_stdout() -> Result<Self>
[src]Duplex with stdin and stdout, taking ownership of them.
Unlike std::io::stdin
and std::io::stdout
, this stdin_stdout
returns a stream which is unbuffered and unlocked.
This acquires a std::io::StdinLock
and a std::io::StdoutLock
(in non-recursive ways) to prevent accesses to std::io::Stdin
and
std::io::Stdout
while this is live, and fails if a StreamReader
for standard input, a StreamWriter
for standard output, or a
StreamDuplexer
for standard input and standard output already exist.
#[must_use]pub fn tcp_stream<Socketlike: IntoUnsafeSocket>(socketlike: Socketlike) -> Self
[src]
#[must_use]pub fn tcp_stream<Socketlike: IntoUnsafeSocket>(socketlike: Socketlike) -> Self
[src]Duplex with an open TCP stream, taking ownership of it.
This method can be passed a std::net::TcpStream
or similar
TcpStream
types.
#[must_use]pub fn unix_stream(unix_stream: UnixStream) -> Self
[src]
#[must_use]pub fn unix_stream(unix_stream: UnixStream) -> Self
[src]Duplex with an open Unix-domain stream, taking ownership of it.
#[must_use]pub fn pipe_reader_writer(
pipe_reader: PipeReader,
pipe_writer: PipeWriter
) -> Self
[src]
#[must_use]pub fn pipe_reader_writer(
pipe_reader: PipeReader,
pipe_writer: PipeWriter
) -> Self
[src]Duplex with a pair of pipe streams, taking ownership of them.
pub fn duplex_with_command(command: Command) -> Result<Self>
[src]
pub fn duplex_with_command(command: Command) -> Result<Self>
[src]Spawn the given command and duplex with its standard input and output.
#[must_use]pub fn child_stdout_stdin(
child_stdout: ChildStdout,
child_stdin: ChildStdin
) -> Self
[src]
#[must_use]pub fn child_stdout_stdin(
child_stdout: ChildStdout,
child_stdin: ChildStdin
) -> Self
[src]Duplex with a child process’ stdout and stdin, taking ownership of them.
