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`

Fields

eval: PlatformEval<'g>

An evaluator to run queries against.

The status is platform-dependent.

Implementations

source

impl<'g> PlatformStatus<'g>

source

pub fn is_always(&self) -> bool

Returns true if this dependency is always enabled on all platforms.

source

pub fn is_never(&self) -> bool

Returns true if this dependency is never enabled on any platform.

source

pub fn is_present(&self) -> bool

Returns true if this dependency is possibly enabled on any platform.

source

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.
