Trait Implementations

impl Debug for NullOutput

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FileDescription for NullOutput

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

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

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

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

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
