| ### [`dump-syntax`](dump-syntax) |
| |
| Little utility to parse a Rust source file into a `syn::File` and print out a |
| debug representation of the syntax tree. |
| |
| ### [`heapsize`](heapsize) |
| |
| A complete working Macros 1.1 implementation of a custom derive. Works on any |
| Rust compiler >=1.15.0. |
| |
| ### [`heapsize2`](heapsize2) |
| |
| The equivalent of the previous example but using fancy new APIs from the nightly |
| compiler. It illustrates some neat features of the hygiene system of Macros 2.0 |
| and shows how to leverage those to provide amazing error messages to users. |
| Currently requires a nightly Rust compiler >=1.24.0-nightly but we are working |
| to stabilize all of the APIs involved. |
| |
| ### [`lazy-static`](lazy-static) |
| |
| An example of parsing a custom syntax within a `functionlike!(...)` procedural |
| macro. Demonstrates how to trigger custom warnings and error messages on |
| individual tokens of the input. |
| |
| ### [`trace-var`](trace-var) |
| |
| An attribute procedural macro that uses a syntax tree traversal to transform |
| certain syntax tree nodes in a function body. |
