Struct rustc_mir_transform::inline::CostChecker
source · struct CostChecker<'b, 'tcx> {
tcx: TyCtxt<'tcx>,
param_env: ParamEnv<'tcx>,
cost: usize,
callee_body: &'b Body<'tcx>,
instance: Instance<'tcx>,
}
Expand description
Verify that the callee body is compatible with the caller.
This visitor mostly computes the inlining cost, but also needs to verify that types match because of normalization failure.

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.
