Public Methods

void ~MapperSession ()

void Close (CloseCallback callback)

Terminates the connection.

After calling `Close`, the client must not send any other requests.

Servers, after sending the status response, should close the connection

regardless of status and without sending an epitaph.

Closing the client end of the channel should be semantically equivalent

to calling `Close` without knowing when the close has completed or its

status.

void CreateVmo (uint64_t size, ::fuchsia::storage::block::CreateVmoOptions options, CreateVmoCallback callback)

Creates a pager-backed VMO of `size` bytes and returns its assigned session `key`.

Page faults on this VMO are handled directly by the driver mapper.

void CloseVmo (uint64_t key)

Closes the pager-backed VMO associated with `key`.

void OpenChildSession (::fidl::InterfaceRequest< ::fuchsia::storage::block::MapperSession> session, ::zx::vmo mapping_vmo, uint64_t parent_key, ::zx::port port, ::zx::vmo delivery_queue, OpenChildSessionCallback callback)

Opens a child mapper session whose reads map through `parent_key` in the parent session.

When a parent session is closed, all child sessions opened from it are closed as well.

void RecordProfile (::fidl::InterfaceRequest< ::fuchsia::storage::block::Recording> recording, RecordProfileCallback callback)

Starts recording an access profile for this mapper session.
