func (*FileMem) Allocate ¶

func (f *FileMem) Allocate(length uint64, kind usage.MemoryKind) (platform.FileRange, error)

Allocate implements platform.Memory.Allocate.

func (*FileMem) DecRef ¶

func (f *FileMem) DecRef(fr platform.FileRange)

DecRef implements platform.File.DecRef.

func (*FileMem) Decommit ¶

func (f *FileMem) Decommit(fr platform.FileRange) error

Decommit implements platform.Memory.Decommit.

func (*FileMem) Destroy ¶

func (f *FileMem) Destroy()

Destroy implements platform.Memory.Destroy.

func (*FileMem) File ¶

func (f *FileMem) File() *os.File

File returns the memory file used by f.

func (*FileMem) Flush ¶

func (f *FileMem) Flush(ctx context.Context) error

Flush implements platform.Mappable.Flush.

func (*FileMem) IncRef ¶

func (f *FileMem) IncRef(fr platform.FileRange)

IncRef implements platform.File.IncRef.

func (*FileMem) LoadFrom ¶

func (f *FileMem) LoadFrom(r io.Reader) error

LoadFrom implements platform.Memory.LoadFrom.

func (*FileMem) MapInternal ¶

func (f *FileMem) MapInternal(fr platform.FileRange, at usermem.AccessType) (safemem.BlockSeq, error)

MapInternal implements platform.File.MapInternal.

func (*FileMem) MapInto ¶

func (f *FileMem) MapInto(as platform.AddressSpace, addr usermem.Addr, fr platform.FileRange, at usermem.AccessType, precommit bool) error

MapInto implements platform.File.MapInto.

func (*FileMem) SaveTo ¶

func (f *FileMem) SaveTo(w io.Writer) error

SaveTo implements platform.Memory.SaveTo.

func (*FileMem) String ¶

func (f *FileMem) String() string

String implements fmt.Stringer.String.

Note that because f.String locks f.mu, calling f.String internally (including indirectly through the fmt package) risks recursive locking. Within the filemem package, use f.usage directly instead.

func (*FileMem) TotalSize ¶

func (f *FileMem) TotalSize() uint64

TotalSize implements platform.Memory.TotalSize.

func (*FileMem) TotalUsage ¶

func (f *FileMem) TotalUsage() (uint64, error)

TotalUsage implements platform.Memory.TotalUsage.

func (*FileMem) UpdateUsage ¶

func (f *FileMem) UpdateUsage() error

UpdateUsage implements platform.Memory.UpdateUsage.
