Function getxattr 

pub fn getxattr<P: Arg, Name: Arg, Buf: Buffer<u8>>(
    path: P,
    name: Name,
    value: Buf,
) -> Result<Buf::Output>

getxattr(path, name, value)—Get extended filesystem attributes.

Unlike the libc getxattr function, this function does not treat an buffer with zero length as a way to return the size of the attribute. To obtain the size, use getxattr_query.

For a higher-level API to xattr functionality, see the xattr crate.
