target-spec
Evaluate Cargo.toml
target specifications against platform triples.
Cargo supports platform-specific dependencies. These dependencies can be specified in one of two ways:
# 1. As Rust-like `#[cfg]` syntax.
[]
= { = "native/x86_64" }
# 2. Listing out the full target triple.
[]
= "0.4.0"
target-spec
provides the eval
API which can be used to figure out whether such a
dependency will be included on a particular platform.
use eval;
// Evaluate Rust-like `#[cfg]` syntax.
let cfg_target = "cfg(all(unix, target_arch = \"x86_64\"))";
assert_eq!;
assert_eq!;
assert_eq!;
// Evaluate a full target-triple.
