Structs

ValTree

An interned valtree. Use this rather than ValTreeKind, whenever possible.

Value

A type-level constant value.

ConstToValTreeResult

Ok(Err(ty)) indicates the constant was fine, but the valtree couldn’t be constructed because the value contains something of type ty that is not valtree-compatible. The caller can then show an appropriate error; the query does not have the necessary context to give good user-facing errors for this case.
