Expand description
Similar to Issue
, but contains some extra information
Variants§
Invalid(ProvidedIdx, ExpectedIdx, Compatibility<'tcx>)
The provided argument is the invalid type for the expected input
Missing(ExpectedIdx)
There is a missing input
Extra(ProvidedIdx)
There’s a superfluous argument
Swap(ProvidedIdx, ProvidedIdx, ExpectedIdx, ExpectedIdx)
Two arguments should be swapped
Permutation(Vec<(ExpectedIdx, ProvidedIdx)>)
Several arguments should be reordered
