pub struct SwitchTargets {
pub(super) values: SmallVec<[Pu128; 1]>,
pub(super) targets: SmallVec<[BasicBlock; 2]>,
}
Fields§
§values: SmallVec<[Pu128; 1]>
Possible values. The locations to branch to in each case
are found in the corresponding indices from the targets
vector.
targets: SmallVec<[BasicBlock; 2]>
Possible branch sites. The last element of this vector is used for the otherwise branch, so targets.len() == values.len() + 1 should hold.
Implementations§
Source§impl SwitchTargets
impl SwitchTargets
Sourcepub fn successors_for_value(&self, value: u128) -> Successors<'_>
pub fn successors_for_value(&self, value: u128) -> Successors<'_>
Like SwitchTargets::target_for_value
, but returning the same type as
Terminator::successors
.
Source§impl SwitchTargets
impl SwitchTargets
Sourcepub fn new(
targets: impl Iterator<Item = (u128, BasicBlock)>,
otherwise: BasicBlock,
) -> Self
pub fn new( targets: impl Iterator<Item = (u128, BasicBlock)>, otherwise: BasicBlock, ) -> Self
Creates switch targets from an iterator of values and target blocks.
The iterator may be empty, in which case the SwitchInt
instruction is equivalent to
goto otherwise;
.
Sourcepub fn static_if(value: u128, then: BasicBlock, else_: BasicBlock) -> Self
pub fn static_if(value: u128, then: BasicBlock, else_: BasicBlock) -> Self
Builds a switch targets definition that jumps to then
if the tested value equals value
,
and to else_
if not.
Sourcepub fn as_static_if(&self) -> Option<(u128, BasicBlock, BasicBlock)>
pub fn as_static_if(&self) -> Option<(u128, BasicBlock, BasicBlock)>
Inverse of SwitchTargets::static_if
.
Sourcepub fn otherwise(&self) -> BasicBlock
pub fn otherwise(&self) -> BasicBlock
Returns the fallback target that is jumped to when none of the values match the operand.
Sourcepub fn iter(&self) -> SwitchTargetsIter<'_> ⓘ
pub fn iter(&self) -> SwitchTargetsIter<'_> ⓘ
Returns an iterator over the switch targets.
The iterator will yield tuples containing the value and corresponding target to jump to, not
including the otherwise
fallback target.
Note that this may yield 0 elements. Only the otherwise
branch is mandatory.
Sourcepub fn all_targets(&self) -> &[BasicBlock]
pub fn all_targets(&self) -> &[BasicBlock]
Returns a slice with all possible jump targets (including the fallback target).
pub fn all_targets_mut(&mut self) -> &mut [BasicBlock]
Sourcepub fn target_for_value(&self, value: u128) -> BasicBlock
pub fn target_for_value(&self, value: u128) -> BasicBlock
Finds the BasicBlock
to which this SwitchInt
will branch given the
specific value. This cannot fail, as it’ll return the otherwise
branch if there’s not a specific match for the value.
Sourcepub fn add_target(&mut self, value: u128, bb: BasicBlock)
pub fn add_target(&mut self, value: u128, bb: BasicBlock)
Adds a new target to the switch. But You cannot add an already present value.
Sourcepub fn is_distinct(&self) -> bool
pub fn is_distinct(&self) -> bool
Returns true if all targets (including the fallback target) are distinct.
