Provided Methods

fn check_shim_sig_lenient<'a, const N: usize>( &mut self, abi: &FnAbi<'tcx, Ty<'tcx>>, exp_abi: CanonAbi, link_name: Symbol, args: &'a [OpTy<'tcx>], ) -> InterpResult<'tcx, &'a [OpTy<'tcx>; N]>

fn check_shim_sig<'a, const N: usize>( &mut self, shim_sig: fn(&MiriInterpCx<'tcx>) -> ShimSig<'tcx, N>, link_name: Symbol, caller_fn_abi: &FnAbi<'tcx, Ty<'tcx>>, caller_args: &'a [OpTy<'tcx>], ) -> InterpResult<'tcx, &'a [OpTy<'tcx>; N]>

Check that the given caller_fn_abi matches the expected ABI described by shim_sig, and then returns the list of arguments.

fn check_shim_sig_variadic_lenient<'a, const N: usize>( &mut self, abi: &FnAbi<'tcx, Ty<'tcx>>, exp_abi: CanonAbi, link_name: Symbol, args: &'a [OpTy<'tcx>], ) -> InterpResult<'tcx, (&'a [OpTy<'tcx>; N], &'a [OpTy<'tcx>])>

where &'a [OpTy<'tcx>; N]: TryFrom<&'a [OpTy<'tcx>]>,

Check shim for variadic function. Returns a tuple that consisting of an array of fixed args, and a slice of varargs.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
