Struct std::io::StdioStream

Standard I/O stream.

Fields

• fd: FileDescriptor

Methods

• fn stdin() -> StdioStream

  source

  Standard input

• fn stdout() -> StdioStream

  source

  Standard output

• fn stderr() -> StdioStream

  source

  Standard error

• fn as_fd(self: &StdioStream) -> FileDescriptor

  source

• fn close(self: &mut StdioStream) -> Result<()>

  source

  Close the stream.

• fn flush(self: &mut StdioStream) -> Result<()>

  source

  Flush the stream.

• fn move(self: &mut StdioStream) -> StdioStream

  source

  Creates a copy of the object, leaving an inert object behind.

  See Movable for details.

Mixins

• mixin FdReadWrite<StdioStream>

• fn read(self: &mut Self, buf: &mut [u8]) -> Result<usize>

  source

  Reads from the stream into a provided buffer.

  If successful, returns the number of bytes read. This may be less than the size of the provided buffer.

• fn write(self: &mut Self, buf: &[u8]) -> Result<usize>

  source

  Write the buffer to the stream.

  Returns the number of bytes written. This may be less than the size of the buffer. See also write_all, which can be used to write the entire buffer.

• mixin Readable<StdioStream>

• fn read_exact(self: &mut Self, buf: &mut [u8]) -> Result<()>

  source

  Fills the provided buffer by reading from the stream.

  If stream had less bytes available than the size of the buffer, this method will return an Error::eof().

• fn read_to_end(self: &mut Self, buf: &mut StringBuf) -> Result<usize>

  source

  Reads the entire stream into a StringBuf.

  If successful, returns the number of bytes that were read.

• mixin Writable<StdioStream>

• fn write_all(self: &mut Self, buf: &[u8]) -> Result<()>

  source

  Writes all the bytes in the buffer to the stream.

  If EOF is reached, returns Error::eof().
