Struct std::io::FileDescriptor

Platform specific file descriptor.

On UNIX platforms this is a wrapper over an integer.

Fields

• value: c_int

Methods

• fn new(value: c_int) -> FileDescriptor

  source

  Create a FileDescriptor object from a raw file descriptor.

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

  source

  Close the file descriptor.

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

  source

• fn set_nonblocking(self: &mut FileDescriptor, nonblocking: bool) -> Result<()>

  source

  Sets the file descriptor blocking mode.

• fn set_cloexec(self: &mut FileDescriptor) -> Result<()>

  source

  Sets whether the file descriptor is closed on exec.

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

  source

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

  See Movable for details.

Mixins

• mixin FdReadWrite<FileDescriptor>

• 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<FileDescriptor>

• 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<FileDescriptor>

• 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().
