pub struct Lattice<T> { /* private fields */ }Expand description
This type adapts a LatticeLike value for use as an AnalysisState by a [DataFlowAnalysis].
Implementations§

impl<T> Lattice<T>
Sourcepub fn new(anchor: LatticeAnchorRef, value: T) -> Self
pub fn new(anchor: LatticeAnchorRef, value: T) -> Self
Construct a new Lattice from the given anchor and LatticeLike value.

Source§impl<T: Default + 'static> BuildableAnalysisState for Lattice<T>
Any type that has a default value is buildable
impl<T: Default + 'static> BuildableAnalysisState for Lattice<T>
Any type that has a default value is buildable
NOTE: The default value is expected to correspond to the minimum state of the lattice, typically a value that represents “unknown” or most conservative state. Otherwise, the implementation of any analyses that depend on the type are likely to reach the overdefined state when they otherwise would not (due to a non-minimal value “conflicting” with the value concluded by the analysis).
