class Server

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 and is *NOT* an unnamed temporary object (objects opened with

`Flags.FLAG_CREATE_AS_UNNAMED_TEMPORARY`), it will fail with `ZX_ERR_NOT_FOUND`.

For unnamed temporary objects, use LinkInto to give it a name. Upon successful completion,

the object will be permanently linked to the filesystem. Requires that the unnamed temporary

object is linkable, if not, 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.

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.

DEPRECATED - Use `fuchsia.unknown/Cloneable.Clone` instead.

DEPRECATED - Use `Node.GetAttributes` instead.

DEPRECATED - Use `Node.UpdateAttributes` instead.

[DEPRECATED - Use new GetFlags method instead.]

[DEPRECATED - Use new SetFlags method instead.]

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.

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.

Query the filesystem for details specific to the filesystem and/or volume. If the current

volume has different settings or the storage is accounted seperately from the rest of the

filesystem that may be reported instead of filesystem-wide details.

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.

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.

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.

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.

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.

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.

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.

|bind_handler| returns a handler that binds incoming connections to this

server implementation.

The returned handler borrows the server instance.

The server must outlive the provided |dispatcher|. Only after

the dispatcher is shutdown will it be safe to destroy the servers.

The server should not be moved.
