[−][src]Enum minitt::ast::Pattern
Patt
in Mini-TT.
$p ::=$
Variants
Pair(Box<Self>, Box<Self>)
$p,p$, Pair pattern. This sounds like trivial and useless, but we can achieve mutual recursion by using this pattern.
Unit
_, Unit pattern, used for introducing anonymous definitions.
Var(String)
$x$, Variable name pattern, the most typical pattern.
