Enum MatchPattern 

pub enum MatchPattern {
    Any,
    Regex {
        pattern: String,
        flags: String,
    },
    Value(Box<Expr>),
    Array(Vec<MatchArrayElem>),
    Hash(Vec<MatchHashPair>),
    OptionSome(String),
}

Pattern for algebraic match (distinct from the =~ / regex ExprKind::Match).

Variants

Any

_ — matches anything.

Regex

/regex/ — subject stringified; on success the arm body sets $_ to the subject and populates match variables ($1…, $&, ${^MATCH}, @-/@+, %+, …) like =~.

Fields

pattern: String

flags: String

Value(Box<Expr>)

Arbitrary expression compared for equality / smart-match against the subject.

Array(Vec<MatchArrayElem>)

[1, 2, *] — prefix elements match; optional * matches any tail (must be last).

Hash(Vec<MatchHashPair>)

{ name => $n, ... } — required keys; $n binds the value for the arm body.

OptionSome(String)

Some($x) — matches array-like values with at least two elements where index 1 is Perl-truthy (stryke: $gen->next yields [value, more] with more truthy while iterating).
