pub enum LoweringFlowError<'db> {
Failed(DiagnosticAdded),
Panic(VarUsage<'db>, LocationId<'db>),
Return(VarUsage<'db>, LocationId<'db>),
Match(MatchInfo<'db>),
}Expand description
Cases where the flow of lowering an expression should halt.
Variants§
Failed(DiagnosticAdded)
Computation failure. A corresponding diagnostic should be emitted.
Panic(VarUsage<'db>, LocationId<'db>)
The expression that was being lowered always panics, and does not flow to the parent builder.
Return(VarUsage<'db>, LocationId<'db>)
The expression that was being lowered always returns from the function, and does not flow to the parent builder.
Match(MatchInfo<'db>)
Every match arm is terminating - does not flow to parent builder e.g. returns or panics.
