Represents an open file descriptor.

Required Methods

fn name(&self) -> &'static str

fn dup(&mut self) -> Result<Box<dyn FileDescriptor>>

fn write<'tcx>( &self, _communicate_allowed: bool, _bytes: &[u8], _tcx: TyCtxt<'tcx> ) -> InterpResult<'tcx, Result<usize>>

fn seek<'tcx>( &mut self, _communicate_allowed: bool, _offset: SeekFrom ) -> InterpResult<'tcx, Result<u64>>

fn close<'tcx>( self: Box<Self>, _communicate_allowed: bool ) -> InterpResult<'tcx, Result<i32>>

fn is_tty(&self, _communicate_allowed: bool) -> bool
