Struct guppy::platform::Platform [−][src]
pub struct Platform { /* fields omitted */ }
Expand description
A platform to evaluate target specs against.
Implementations
Creates a new Platform
from the given triple and target features.
Returns an error if this platform wasn’t known to target-spec
.
Returns the current platform, as detected at build time.
This will return an error if the current platform was unknown to this version of
target-spec
.
Creates a new platform from a Triple
and target features.
Adds a set of flags to accept.
A flag is a single token like the foo
in cfg(not(foo))
.
A default cargo build
will always evaluate flags to false, but custom wrappers may cause
some flags to evaluate to true. For example, as of version 0.6, cargo web build
will cause
cargo_web
to evaluate to true.
Returns the target triple string for this platform.
Returns the set of flags enabled for this platform.
Returns true if this flag was set with add_flags
.
Returns the set of target features for this platform.
Helpers for property testing
The methods in this section allow Platform
instances to be used in property-based testing
scenarios.
Currently, proptest 1 is supported if the proptest1
feature is enabled.
Given a way to generate TargetFeatures
instances, this returns a Strategy
that generates
a platform at random.
Requires the proptest1
feature to be enabled.
Examples
use proptest::prelude::*;
use target_spec::{Platform, TargetFeatures};
// target_features is a strategy that always produces TargetFeatures::Unknown.
let target_features = Just(TargetFeatures::Unknown);
let strategy = Platform::strategy(target_features);
pub fn filtered_strategy(
triple_filter: impl Fn(&'static str) -> bool,
target_features: impl Strategy<Value = TargetFeatures>
) -> impl Strategy<Value = Platform>
pub fn filtered_strategy(
triple_filter: impl Fn(&'static str) -> bool,
target_features: impl Strategy<Value = TargetFeatures>
) -> impl Strategy<Value = Platform>
A version of strategy
that allows target triples to be filtered.
Requires the proptest1
feature to be enabled.
Converts this Platform
to a serializable form.
Requires the summaries
feature to be enabled.
