Expand description

Tracker trait to provide Source-es with unique IDs

Out of the box crate::core::Primary implements this trait for you, but you can also roll your own.

structs like crate::basic::Track and crate::basic::Clip take a &mut dyn Tracker as their first argument during construction to generate a unique ID

Required methods

Return a unique ID

clear source id for reuse

get signal for id

set signal for id
