Enum ra_ap_hir::CfgAtom [−][src]
pub enum CfgAtom { Flag(SmolStr), KeyValue { key: SmolStr, value: SmolStr, }, }
Expand description
A simple configuration value passed in from the outside.
Variants
eg. #[cfg(test)]
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")]
.
Implementations
impl CfgAtom
[src]
impl CfgAtom
[src]pub fn is_target_defined(&self) -> bool
[src]
pub fn is_target_defined(&self) -> bool
[src]Returns true
when the atom comes from the target specification.
If this returns true
, then changing this atom requires changing the compilation target. If
it returns false
, the atom might come from a build script or the build system.
