Module show_notes::e010

Macros rule!

• Date: 2016-01-18
• Subject: Using Rust's macro system, its limitations, and its future.
• Audio

Notes

Because of the way macros are exported---before name resolution on crates occurs---the documentation for the macros defined in the source for this episode occurs in the Macros section of the show_notes crate documentation, rather than within the documentation for this module. (See the Rust Book discussion of documenting macros for details.) Even so, the source is still in this module; see the implementations for details.
