Provided Methods

fn check_shim_symbol_clash(&self, link_name: Symbol) -> InterpResult<'tcx, ()>

Ensure the given symbol is not exported by the program.

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.

fn check_shim_sig_unadjusted<'a, const N: usize>( &mut self, link_name: Symbol, args: &'a [OpTy<'tcx>], ) -> InterpResult<'tcx, &'a [OpTy<'tcx>; N]>

Check that the given function has the expected amount of arguments, and then return the list of arguments.

This may only be used for extern "unadjusted" LLVM intrinsics.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
