Why

Matcher composition remains inspectable before runtime compilation.

Ownership and lifetime

MatchAst describes plain readonly AST data. Routes and Matchers retain the concrete nodes they receive by reference; the type itself owns no resource.

Members

• MatchAst.Catch

  A Match AST node defining a reactive cause boundary.

• MatchAst.Layer

  A Match AST boundary carrying route-local Effect Layers.

• MatchAst.Layout

  A function that wraps matched content using reactive params.

• MatchAst.Prefixed

  A Match AST node that structurally prefixes nested cases.

• MatchAst.Route

  A Match AST candidate containing one Route AST, Guard, and output handler.
