Struct UnidentifiedAtom 

pub struct UnidentifiedAtom<'a> { /* private fields */ }

An atom of yet unknown type.

This is used by reading handles that have to return a reference to an atom, but can not check it’s type. This struct contains a Space containing the header and the body of the atom and can identify/read the atom from it.

Implementations

impl<'a> UnidentifiedAtom<'a>

pub fn new(space: Space<'a>) -> Self

Construct a new unidentified atom.

The space actually has to contain an atom. If it doesn’t, crazy (but not undefined) things can happen.

pub fn read<'b, A: Atom<'a, 'b>>( self, urid: URID<A>, parameter: A::ReadParameter, ) -> Option<A::ReadHandle>

Try to read the atom.

To identify the atom, it’s URID and an atom-specific parameter is needed. If the atom was identified, a reading handle is returned.

pub fn type_urid(self) -> Option<URID>

Retrieve the type URID of the atom.

This can be used to identify atoms without actually reading them.

Trait Implementations

impl<'a> Clone for UnidentifiedAtom<'a>

fn clone(&self) -> UnidentifiedAtom<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
