pub struct BlackBoard<'a, Section: Hash + Eq, Type> { /* private fields */ }

Represents a blackboard where processes can post and get items in sections, and also subscribe for changes in a specific section.

Implementations

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, )

Suscribes a function to the specified section. When a post to that section occurs, the function passed in is called with the newly posted value as argument

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

Trait Implementations

impl<'a, Section, Type> Drop for BlackBoard<'a, Section, Type>

where Section: Hash + Eq,

fn drop(&mut self)

Executes the destructor for this type.
