| 2 | |
| 3 | Little utility to parse a Rust source file into a `syn::File` and print out a |
| 4 | debug representation of the syntax tree. |
| 5 | |
| 6 | ### [`heapsize`](heapsize) |
| 7 | |
| 8 | A complete working Macros 1.1 implementation of a custom derive. Works on any |
| 9 | Rust compiler >=1.15.0. |
| 10 | |
| 11 | ### [`heapsize2`](heapsize2) |
| 12 | |
| 13 | The equivalent of the previous example but using fancy new APIs from the nightly |
| 14 | compiler. It illustrates some neat features of the hygiene system of Macros 2.0 |
| 15 | and shows how to leverage those to provide amazing error messages to users. |
| 16 | Currently requires a nightly Rust compiler >=1.24.0-nightly but we are working |
| 17 | to stabilize all of the APIs involved. |
