Required Methods

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

Provided Methods

fn read<'tcx>( &mut self, _communicate_allowed: bool, _bytes: &mut [u8], _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Result<usize>>

Reads as much as possible into the given buffer, and returns the number of bytes read.

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

Writes as much as possible from the given buffer, and returns the number of bytes written.

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

Seeks to the given offset (which can be relative to the beginning, end, or current position). Returns the new position from the start of the stream.

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

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