Enum TestBranch

enum TestBranch<'tcx> {
    Success,
    Constant(Const<'tcx>, u128),
    Variant(VariantIdx),
    Failure,
}

The branch to be taken after a test.

Variants

Success

Success branch, used for tests with two possible outcomes.

Constant(Const<'tcx>, u128)

Branch corresponding to this constant.

Variant(VariantIdx)

Branch corresponding to this variant.

Failure

Failure branch for tests with two possible outcomes, and “otherwise” branch for other tests.

Implementations

impl<'tcx> TestBranch<'tcx>

fn as_constant(&self) -> Option<&Const<'tcx>>

Trait Implementations

impl<'tcx> Clone for TestBranch<'tcx>

fn clone(&self) -> TestBranch<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for TestBranch<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx> Hash for TestBranch<'tcx>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'tcx> PartialEq for TestBranch<'tcx>

fn eq(&self, other: &TestBranch<'tcx>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
