Module types 

AST-based type analysis utilities.

All wrapper extraction operates on syn::Type AST nodes by checking the final path segment ident — never on a string representation of the type. This means Json<T>, axum::Json<T>, and axum::extract::Json<T> are all matched identically.

Structs

Functions

extract_first_generic_arg_string

Extract the first generic argument from a type string.

extract_wrapper

Extract the generic arguments of wrapper_name<...> from ty, or return a structured error if the wrapper is not present or has no type arguments.

innermost_custom_type

Recursively unwrap well-known wrappers and return the innermost type.

is_primitive

Returns true for Rust primitive types and the unit type ().

is_primitive_type_name

Check if a type name string represents a Rust primitive or standard type.

last_ident_matches

Check if the last path segment ident matches the given name.

try_extract_wrapper

Extract the generic arguments of wrapper_name<...> from ty.
