A macro for defining #[cfg] if-else functions.
The macro provided by this crate.
Unlike cfg_if,
cfg_iif can be used as a function, and can be used in a function.
#[cfg()]a_iif is "unix" when a os is Unix at compile time:
rust
use cfg_iif::cfg_iif;
let a_iif = cfg_iif!(#[cfg(Unix)] { "unix" } else { "not unix" });
a_iif is "abc" when a feature is "has_abc" at compile time:
rust
use cfg_iif::cfg_iif;
let a_iif = cfg_iif!(#[cfg(feature = "has_abc")] { "abc" } else { "not abc" });
a_iif is "abc" when a feature is "hasabc" at compile time:
```rust
use cfgiif::cfgiif;
let mut aiif = "";
cfg_iif!(
{ a_iif = "abc"; } ); ```
cargo fmta_iif is "abc" when a feature is "has_abc" at compile time:
rust
use cfg_iif::cfg_iif;
let a_iif = cfg_iif!(feature = "has_abc" { "abc" } else { "not abc" });
a_iif is "abc" when a feature is "has_abc" at compile time:
rust
use cfg_iif::cfg_iif;
let mut a_iif = "";
cfg_iif!(feature = "has_abc" {
a_iif = "abc";
});
