interface Prefixed {
type: "prefixed";
matches: ReadonlyArray<MatchAst>;
prefix: RouteAst;
}Why
Nested route tables can be mounted without rewriting each child route.
Ownership and lifetime
Prefixed describes plain readonly AST data. Routes and Matchers retain the concrete nodes they receive by reference; the type itself owns no resource.
Property: matches
The ordered child matcher nodes wrapped by this boundary.
Property: matches: Why
Order is preserved for candidate and guard fallthrough.
Property: matches: Ownership and lifetime
The prefix boundary retains this ordered child array by reference and applies the prefix only during structural compilation.
Property: prefix
The Route AST prepended to nested matcher cases.
Property: prefix: Why
Prefixing remains structural and participates in schema/path compilation.
Property: prefix: Ownership and lifetime
The prefix Route AST is retained by reference and owns no decoded parameter state.
Property: type
The discriminant identifying this AST variant.
Property: type: Why
Exhaustive switches can interpret syntax without instanceof checks or hidden classes.
