Struct fidl_fuchsia_io::Node2Proxy

pub struct Node2Proxy { /* private fields */ }

Implementations

impl Node2Proxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for Node2

pub fn take_event_stream(&self) -> Node2EventStream

Get a Stream of events from the remote end of the Node2 protocol

Panics

Panics if the event stream was already taken.

pub fn close(&self) -> QueryResponseFut<CloseableCloseResult>

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.

pub fn query(&self) -> QueryResponseFut<Vec<u8>>

pub fn reopen( &self, rights_request: Option<&mut RightsRequest>, object_request: ServerEnd<NodeMarker> ) -> Result<(), Error>

Creates another connection to the same node.

• object_request is the server end of a channel created for the new connection. The caller may proceed to send messages on the corresponding client end right away.

pub fn get_connection_info(&self) -> QueryResponseFut<ConnectionInfo>

Acquires information about the connection.

This method does not require any rights.

pub fn get_attributes( &self, query: NodeAttributesQuery ) -> QueryResponseFut<Node2GetAttributesResult>

Acquires information about the node.

The attributes of a node should be stable, independent of the specific protocol used to access it.

If a particular attribute is not applicable or not supported, filesystems should leave the corresponding field absent.

• query a bit-mask specifying which attributes to fetch. The server should not return more than necessary.

• attributes the returned attributes.

This method requires the [Rights.GET_ATTRIBUTES] right.

pub fn update_attributes( &self, payload: MutableNodeAttributes ) -> QueryResponseFut<Node2UpdateAttributesResult>

Updates information about the node.

• attributes the presence of a table field in attributes indicates the intent to update the corresponding attribute.

This method requires the [Rights.UPDATE_ATTRIBUTES] right.

pub fn sync(&self) -> QueryResponseFut<Node2SyncResult>

Synchronizes updates to the node to the underlying media, if it exists.

This method will return when the filesystem server has flushed the relevant updates to the underlying media, but does not guarantee the underlying media has persisted the information, nor that any information is committed to hardware. Clients may use Sync to ensure ordering between operations.

This method does not require any rights.
