Various Patterns

Trivia maintains a full compatibility with Optima. If you are already familier with Optima, there is no need to understand anything new, other than the additional patterns introduced in Trivia. As the baseline, this page describe the syntax of macro match and its variants. In the following sections, I briefly summarize what kind of patterns are available in these matcher macros.

• Type-Based Destructuring Patterns (In addition to the Optima’s pattern, Trivia has soft-match variants and specialized variants of vector patterns)
• Logic Based Patterns
• Special Patterns (place pattern, bind pattern and access pattern)
