Expand description
A convenience macro to ergonomically define an item depending on a large
number of #[cfg]
parameters. Structured like match statement, the first
matching branch is the item that gets emitted.
Macros
The macro provided by this crate, match_cfg
, is similar to the if/elif
C
preprocessor directives and allows defining a cascade of #[cfg]
cases,
emitting the implementation which matches first.
