Enum guppy::platform::PlatformStatus

pub enum PlatformStatus<'g> {
    Never,
    Always,
    PlatformDependent {
        eval: PlatformEval<'g>,
    },
}

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

impl<'g> PlatformStatus<'g>

pub fn is_always(&self) -> bool

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

pub fn is_never(&self) -> bool

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

pub fn is_present(&self) -> bool

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

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.
