macro_rules! f { ($p:expr) => { ... }; }
Expand description
Convert an unambiguous callable path
into RawIdentifiers.
f! is a short-hand for “function-like”. It’s the macro used to specify a function or a method
to be used as a constructor, request handler, etc.
Use t!, instead, to specify a type when invoking Blueprint::prebuilt.
§Guide
In the “Cookbook”
section of Pavex’s guide on dependency injection
you can find a collection of reference examples on how to use f! macro to register different kinds of
callables (functions, methods, trait methods, etc.) with a Blueprint.
