Enum Pat

pub enum Pat {
    At(String, Vec<Pat>),
    Bind(String),
    Otherwise,
}

A Pat is a pattern for a match expression.

Notably different about Bitsy from other languages with a match or case statement, constructors and constant patterns are prefixed by an @ symbol to distinguish them from variable bindings. For instance:

• @Valid(n)
• @Invalid
• @Opcode::OP

Variants

At(String, Vec<Pat>)

Bind(String)

Otherwise
