Struct MetadataHandle

pub struct MetadataHandle {
    pub(crate) meta: Metadata,
}

Windows supports handles without any read/write/delete permissions - these handles can get metadata, but little else. We represent that by storing the metadata from the time the handle was opened.

Fields

meta: Metadata

Trait Implementations

impl Debug for MetadataHandle

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

Formats the value using the given formatter.

impl FileDescription for MetadataHandle

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

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

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

Close the file descriptor.

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 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

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.
