Trait Implementations

impl Debug for DirHandle

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

Formats the value using the given formatter.

impl FileDescription for DirHandle

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

fn metadata<'tcx>( &self, ) -> InterpResult<'tcx, Either<Result<Metadata>, &'static str>>

Returns the metadata for this FD, if available. This is either host metadata, or a non-file-backed-FD type. The latter is for new represented as a string storing a libc name so we only support that kind of metadata on Unix targets.

fn destroy<'tcx>( self, _self_id: FdId, _communicate_allowed: bool, _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Result<()>>

Destroys the file description. Only called when the last duplicate file descriptor is closed.

fn read<'tcx>( self: FileDescriptionRef<Self>, _communicate_allowed: bool, _ptr: Pointer, _len: usize, _ecx: &mut MiriInterpCx<'tcx>, _finish: DynMachineCallback<'tcx, Result<usize, IoError>>, ) -> InterpResult<'tcx>

Reads as much as possible into the given buffer ptr. len indicates how many bytes we should try to read.

fn write<'tcx>( self: FileDescriptionRef<Self>, _communicate_allowed: bool, _ptr: Pointer, _len: usize, _ecx: &mut MiriInterpCx<'tcx>, _finish: DynMachineCallback<'tcx, Result<usize, IoError>>, ) -> InterpResult<'tcx>

Writes as much as possible from the given buffer ptr. len indicates how many bytes we should try to write.

fn short_fd_operations(&self) -> bool

Determines whether this FD non-deterministically has its reads and writes shortened.

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.

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

fn as_unix<'tcx>(&self, _ecx: &MiriInterpCx<'tcx>) -> &dyn UnixFileDescription

fn get_flags<'tcx>( &self, _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Scalar>

Implementation of fcntl(F_GETFL) for this FD.

fn set_flags<'tcx>( &self, _flag: i32, _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Scalar>

Implementation of fcntl(F_SETFL) for this FD.

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.
