Implementations

impl Content

pub fn atoms() -> Self

Creates new empty content of type Self::Atoms.

pub fn atom(atom: Atom) -> Self

pub fn data_atom_with(data: Data) -> Self

Creates new content of type Self::Atoms containing a data Atom with the data.

pub fn atom_with(ident: Ident, offset: usize, content: Self) -> Self

Creates new content of type Self::Atoms containing a new Atom with the identifier, offset and content.

pub fn add_atom(self, atom: Atom) -> Self

Adds the atom to the list of children atoms if self is of type Self::Atoms.

pub fn add_atom_with(self, ident: Ident, offset: usize, content: Self) -> Self
