Public Methods

bool IsEmpty ()

Returns whether no field is set.

bool HasUnknownData ()

Returns whether the table references unknown fields.

::fidl::WireTableBuilder< ::fuchsia_sysmem2::wire::VmoBuffer> Builder (::fidl::AnyArena & arena)

Return a builder that by defaults allocates of an arena.

::fidl::WireTableExternalBuilder< ::fuchsia_sysmem2::wire::VmoBuffer> ExternalBuilder (::fidl::ObjectView< ::fidl::WireTableFrame< ::fuchsia_sysmem2::wire::VmoBuffer>> frame)

Return a builder that relies on explicitly allocating |fidl::ObjectView|s.

::zx::vmo & vmo ()

`vmo` can be un-set if a participant has only

[`fuchsia.sysmem2/BufferUsage.none`] set to `NONE_USAGE` (explicitly or

implicitly by [`fuchsia.sysmem2/BufferCollection.SetConstraints`]

without `constraints` set).

uint64_t & vmo_usable_start ()

Offset within the VMO of the first usable byte. Must be

the VMO's size

in bytes, and leave sufficient room for BufferMemorySettings.size_bytes

before the end of the VMO.

Currently sysmem will always set this field to 0, and in future, sysmem

won't set this field to a non-zero value unless all participants have

explicitly indicated support for non-zero vmo_usable_start (this

mechanism does not exist as of this comment). A participant that hasn't

explicitly indicated support for non-zero vmo_usable_start (all current

clients) should implicitly assume this field is set to 0 without

actually checking this field.

::zx::eventpair & close_weak_asap ()

This field is set iff `vmo` is a sysmem weak VMO handle. The client must

keep `close_weak_asap` around for as long as `vmo`, and must notice

`ZX_EVENTPAIR_PEER_CLOSED`. If that signal occurs, the client must close

`vmo` asap. Not doing so is considered a VMO leak by the client and in

that case sysmem will eventually complain loudly via syslog (currently

5s later).

VmoBuffer & clear_close_weak_asap ()

void VmoBuffer (::fidl::AnyArena & allocator)

void VmoBuffer (::fidl::ObjectView< ::fidl::WireTableFrame< ::fuchsia_sysmem2::wire::VmoBuffer>> && frame)

This constructor allows a user controlled allocation (not using a Arena).

It should only be used when performance is key.

As soon as the frame is given to the table, it must not be used directly or for another table.
