pub fn data_atom_with(data: Data) -> Content

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

pub fn atom_with(head: [u8; 4], offset: usize, content: Content) -> Content

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

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

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

pub fn add_data_atom(self) -> Content

Adds a data Atom to the list of children if self is of type Content::Atoms.

pub fn add_atom_with(
    self,
    head: [u8; 4],
