impl<'a, Section, Type> BlackBoard<'a, Section, Type> where
    Section: Hash + Eq, 

pub fn new() -> Self

Generates a new, empty blackboard

pub fn get(&self, section: &Section) -> Option<&Vec<Type>>

Gets the section, if it exists.

pub fn get_sections(&self) -> Vec<&Section>

Returns a list of all the sections present right now in the BlackBoard

pub fn post(&mut self, section: Section, what: Type)

Posts data on the desired section. Note that data is consumed

pub fn subscribe(
    &mut self,
    section: Section,
    subscriptor: impl Subscriptor<Type> + 'a
)

    &mut self,
    section: Section,
    subscriptor: &Rc<impl Subscriptor<Type> + 'a>
)
