Variants§

§

Switch

Fields

§adt_def: AdtDef<'tcx>

The enum type being tested.

§variants: BitSet<VariantIdx>

The set of variants that we should create a branch for. We also create an additional “otherwise” case.

Test what enum variant a value is.

§

SwitchInt

Fields

§switch_ty: Ty<'tcx>

The type of the value that we’re testing.

§options: FxIndexMap<Const<'tcx>, u128>

The (ordered) set of values that we test for.

For integers and chars we create a branch to each of the values in options, as well as an “otherwise” branch for all other values, even in the (rare) case that options is exhaustive.

For bool we always generate two edges, one for true and one for false.

Test what value an integer, bool, or char has.

§

Eq

Fields

§value: Const<'tcx>
§ty: Ty<'tcx>

Test for equality with value, possibly after an unsizing coercion to ty,

§

Range(Box<PatRange<'tcx>>)

Test whether the value falls within an inclusive or exclusive range

§

Len

Fields

§len: u64

Test that the length of the slice is equal to len.
