A [‘Node’] which contains a symbolic link.

Variants

LinkInto

Creates a link to this this object with name dst in the directory represented by dst_parent_token.

dst must be a resolved object name. Including “/” in the string will return ZX_ERR_INVALID_ARGS.

This method requires the maximal set of rights supported by the filesystem for this object. For files this would typically be [Rights.READ_BYTES], [Rights.WRITE_BYTES], [Rights.GET_ATTRIBUTES] and [Rights.UPDATE_ATTRIBUTES]. Some filesystems might also support the [Rights.EXECUTE] right. Insufficient rights will result in ZX_ERR_ACCESS_DENIED.

If this object has no links, it will fail with ZX_ERR_NOT_FOUND.

This method does not have the same atomicity properties has the Directory::Link method, which means that calling Open then LinkInto is not equivalent to Directory::Link because LinkInto will not prevent the source from being renamed or unlinked.

Fields

dst_parent_token: Event

dst: String

responder: SymlinkLinkIntoResponder

Clone

Fields

request: ServerEnd<CloneableMarker>

control_handle: SymlinkControlHandle

Close

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.

Fields

responder: SymlinkCloseResponder

Query

Fields

responder: SymlinkQueryResponder

DeprecatedClone

Fields

flags: OpenFlags

object: ServerEnd<NodeMarker>

control_handle: SymlinkControlHandle

GetAttr

Acquires information about the node.

This method does not require any rights.

Fields

responder: SymlinkGetAttrResponder

SetAttr

Updates information about the node.

Returns ZX_ERR_NOT_SUPPORTED if any attributes specified by [flags] are not supported.

This method requires following rights: OpenFlags.RIGHT_WRITABLE, otherwise returns ZX_ERR_BAD_HANDLE.

Fields

flags: NodeAttributeFlags

attributes: NodeAttributes

responder: SymlinkSetAttrResponder

GetFlags

Acquires the Directory.Open rights and flags used to access this file.

This method does not require any rights.

Fields

responder: SymlinkGetFlagsResponder

SetFlags

Changes the Directory.Open flags used to access the file. Supported flags which can be turned on / off:

• OpenFlags.APPEND

This method does not require any rights.

Fields

flags: OpenFlags

responder: SymlinkSetFlagsResponder

GetFlags2

Queries the flags that apply to this node after it has been opened/created. This method does not require any rights.

Note that the final set of flags that apply to the connection may differ from those specified with the fuchsia.io/Directory.Open request used to create it:

• Flags.PERM_INHERIT_*: Only applies when determining connection rights.
• Flags.PROTOCOL_*: Only the protocol of the connection will be present.
• Flags.FLAG_*: Only applies when opening the resource, not part of the connection.

Fields

responder: SymlinkGetFlags2Responder

SetFlags2

Sets the flags that apply to this node after it has been opened. This method does not require any rights.

Only Flags.FILE_APPEND is currently supported. Calling this method without any flags will clear append mode.

Errors:

• ZX_ERR_NOT_SUPPORTED: The object does not support this feature or the specified flags.
• ZX_ERR_INVALID_ARGS: flags other than Flags.FILE_APPEND were specified.

Fields

flags: Flags

responder: SymlinkSetFlags2Responder

QueryFilesystem

Query the filesystem for filesystem-specific information.

Fields

responder: SymlinkQueryFilesystemResponder

GetConnectionInfo

Acquires information about the connection.

This method does not require any rights.

Fields

responder: SymlinkGetConnectionInfoResponder

GetAttributes

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.

Fields

query: NodeAttributesQuery

responder: SymlinkGetAttributesResponder

UpdateAttributes

Updates information about the node.

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

Returns ZX_ERR_NOT_SUPPORTED if the node does not support any of the specified attributes.

This method requires the [Rights.UPDATE_ATTRIBUTES] right.

Fields

payload: MutableNodeAttributes

responder: SymlinkUpdateAttributesResponder

Sync

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.

Fields

responder: SymlinkSyncResponder

ListExtendedAttributes

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.

Fields

iterator: ServerEnd<ExtendedAttributeIteratorMarker>

control_handle: SymlinkControlHandle

GetExtendedAttribute

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.

Fields

name: Vec<u8>

responder: SymlinkGetExtendedAttributeResponder

SetExtendedAttribute

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.

Fields

name: Vec<u8>

value: ExtendedAttributeValue

mode: SetExtendedAttributeMode

responder: SymlinkSetExtendedAttributeResponder

RemoveExtendedAttribute

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.

Fields

name: Vec<u8>

responder: SymlinkRemoveExtendedAttributeResponder

Describe

Fields

responder: SymlinkDescribeResponder

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: SymlinkControlHandle

method_type: MethodType
