Module types 

Type rendering utilities for converting rustdoc types to string representations.

This module provides the TypeRenderer struct to convert the complex type structures from rustdoc JSON into human-readable Rust type syntax. These rendered strings are used in the generated markdown documentation.

Overview

Rustdoc JSON represents types as a tree structure (the Type enum). The TypeRenderer walks that tree and produces the string representation you’d write in code.

Usage

let renderer = TypeRenderer::new(&krate);
let type_string = renderer.render_type(&some_type);
let generics = renderer.render_generics(&generic_params);

Example Transformations

Rustdoc Type	Rendered String
Type::Primitive("u32")	"u32"
Type::BorrowedRef { lifetime: Some("'a"), is_mutable: true, type_: ... }	"&'a mut T"
Type::ResolvedPath { path: "Vec", args: ... }	"Vec<T>"

Performance

Uses Cow<str> to avoid allocations for simple types like primitives, generics, and inferred types. Complex types that require string building return owned strings.
