Provided methods
fn getattr(&mut self, _inode: INode) -> FSResult<FileAttributes>
fn setattr(
&mut self,
_inode: INode,
_attr: SetFileAttributes
) -> FSResult<FileAttributes>
fn setxattr(

_attr_name: &OsStr,
_attr_value: &[u8],
_flags: SetXAttrFlags
) -> FSResult<()>
When max_len == 0
, this is functionally requesting only the length of the requested
attribute.
When max_len
is 0, the return value should be an empty string and the length of all the
attributes with an additional nul byte.
When max_len
is greater than 0, this function should return an OsString
composed of all
the xattr names seperated by a nul (\0) byte. If the length of that string is greater than
max_len
, however, the method should error and return FSError::BufferWouldOverflow
.
Reads a directory.
Warning
This method must include the “.” and “..” directories, as well as properly accounting
for offset
. If not, some operations may get stuck in an infinite loop while trying to
read a directory.
