Required methods

pub fn of_fn_ptr(cx: &C, sig: PolyFnSig<'tcx>, extra_args: &[Ty<'tcx>]) -> Self[src]

Compute a FnAbi suitable for indirect calls, i.e. to fn pointers.

NB: this doesn't handle virtual calls - those should use FnAbi::of_instance instead, where the instance is a InstanceDef::Virtual.

pub fn of_instance(
    cx: &C,
    instance: Instance<'tcx>,
    extra_args: &[Ty<'tcx>]
) -> Self[src]

Compute a FnAbi suitable for declaring/defining an fn instance, and for direct calls to an fn.

NB: that includes virtual calls, which are represented by "direct calls" to a InstanceDef::Virtual instance (of <dyn Trait as Trait>::fn).

pub fn new_internal(
    cx: &C,
    sig: PolyFnSig<'tcx>,
    extra_args: &[Ty<'tcx>],
    caller_location: Option<Ty<'tcx>>,
    codegen_fn_attr_flags: CodegenFnAttrFlags,
    mk_arg_type: impl Fn(Ty<'tcx>, Option<usize>) -> ArgAbi<'tcx, Ty<'tcx>>
) -> Self[src]

pub fn adjust_for_abi(&mut self, cx: &C, abi: SpecAbi)[src]
