pub struct Node2Proxy { /* private fields */ }

Implementations§

source§

impl Node2Proxy

source

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.io/Node2.

source

pub fn take_event_stream(&self) -> Node2EventStream

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

§Panics

Panics if the event stream was already taken.

source

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.

source

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

source

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

Creates another connection to the same node.

source

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

Acquires information about the connection.

This method does not require any rights.

source

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.

source

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.

source

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.

source

pub fn list_extended_attributes( &self, iterator: ServerEnd<ExtendedAttributeIteratorMarker> ) -> Result<(), Error>

Creates an iterator over all the extended attribute names associated with this node. If an error occurs it is returned as an epitaph on the iterator request channel, and then the channel is closed.

GetExtendedAttributes can be used with any of these names to retrieve the associated value.

This method requires the [Rights.GET_ATTRIBUTES] right.

source

pub fn get_extended_attribute( &self, name: &[u8] ) -> QueryResponseFut<Node2GetExtendedAttributeResult>

Get the value associated with the given attribute name for this node.

Attribute names have a maximum length of MAX_ATTRIBUTE_NAME. No particular structure is imposed on them.

This method requires the [Rights.GET_ATTRIBUTES] right.

source

pub fn set_extended_attribute( &self, name: &[u8], value: ExtendedAttributeValue, mode: SetExtendedAttributeMode ) -> QueryResponseFut<Node2SetExtendedAttributeResult>

Set the value for the given attribute name to value for this node.

The attribute name may exist, in which case the attribute is updated. If the attribute doesn’t exist, it is created. The name should have no null bytes in it. If it does, ZX_ERR_INVALID_ARGS is returned.

This method requires the [Rights.UPDATE_ATTRIBUTES] right.

source

pub fn remove_extended_attribute( &self, name: &[u8] ) -> QueryResponseFut<Node2RemoveExtendedAttributeResult>

Remove the specified extended attribute.

If the attribute doesn’t exist, ZX_ERR_NOT_FOUND is returned.

This method requires the [Rights.UPDATE_ATTRIBUTES] right.
