Methods
impl TargetPredicate
[src]
pub fn matches(self, target: &TargetInfo) -> bool
[src]
Returns true of the predicate matches the specified target
use cfg_expr::{targets::*, expr::TargetPredicate as tp}; let win = get_target_by_triple("x86_64-pc-windows-msvc").unwrap(); assert!( tp::Arch(Arch::x86_64).matches(win) && tp::Endian(Endian::little).matches(win) && tp::Env(Some(Env::msvc)).matches(win) && tp::Family(Some(Family::windows)).matches(win) && tp::Os(Some(Os::windows)).matches(win) && tp::PointerWidth(64).matches(win) && tp::Vendor(Some(Vendor::pc)).matches(win) );
