pub enum PlatformStatus<'g> {
Never,
Always,
PlatformDependent {
eval: PlatformEval<'g>,
},
}
Expand description
The status of a dependency or feature, which is possibly platform-dependent.
This is a sub-status of EnabledStatus
.
Variants§
Never
This dependency or feature is never enabled on any platforms.
Always
This dependency or feature is always enabled on all platforms.
PlatformDependent
The status is platform-dependent.
Fields
§
eval: PlatformEval<'g>
An evaluator to run queries against.
Implementations§
Source§impl<'g> PlatformStatus<'g>
impl<'g> PlatformStatus<'g>
Sourcepub fn is_always(&self) -> bool
pub fn is_always(&self) -> bool
Returns true if this dependency is always enabled on all platforms.
Sourcepub fn is_never(&self) -> bool
pub fn is_never(&self) -> bool
Returns true if this dependency is never enabled on any platform.
Sourcepub fn is_present(&self) -> bool
pub fn is_present(&self) -> bool
Returns true if this dependency is possibly enabled on any platform.
Sourcepub fn enabled_on(&self, platform_spec: &PlatformSpec) -> EnabledTernary
pub fn enabled_on(&self, platform_spec: &PlatformSpec) -> EnabledTernary
Evaluates whether this dependency is enabled on the given platform spec.
Returns Unknown
if the result was unknown, which may happen if evaluating against an
individual platform and its target features are unknown.
