pub enum CfgAtom {
Flag(SmolStr),
KeyValue {
key: SmolStr,
value: SmolStr,
},
}
Expand description
A simple configuration value passed in from the outside.
Variants§
Flag(SmolStr)
eg. #[cfg(test)]
KeyValue
eg. #[cfg(target_os = "linux")]
Note that a key can have multiple values that are all considered “active” at the same time.
For example, #[cfg(target_feature = "sse")]
and #[cfg(target_feature = "sse2")]
.
