Struct rustc_typeck::check::closure::ClosureSignatures

source · 
struct ClosureSignatures<'tcx> {
    bound_sig: PolyFnSig<'tcx>,
    liberated_sig: FnSig<'tcx>,
}

Fields

bound_sig: PolyFnSig<'tcx>

The signature users of the closure see.

liberated_sig: FnSig<'tcx>

The signature within the function body. This mostly differs in the sense that lifetimes are now early bound and any opaque types from the signature expectation are overriden in case there are explicit hidden types written by the user in the closure signature.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
