fn write<'tcx>( &self, _self_ref: &FileDescriptionRef, _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 read<'tcx>( &self, _self_ref: &FileDescriptionRef, _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 pread<'tcx>( &self, _communicate_allowed: bool, _bytes: &mut [u8], _offset: u64, _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Result<usize>>
Reads as much as possible into the given buffer from a given offset,
and returns the number of bytes read.

fn pwrite<'tcx>( &self, _communicate_allowed: bool, _bytes: &[u8], _offset: u64, _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Result<usize>>
Writes as much as possible from the given buffer starting at a given offset,
and returns the number of bytes written.

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

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.
