pub struct MirScalarExprDeserializeContext;Expand description
Extends the test case syntax to support MirScalarExprs
The following variants of MirScalarExpr have non-standard syntax:
Literal -> the syntax is (ok <literal> <scalar type>), <literal>
or (err ok token can be omitted.
If <scalar type> is not specified, then literals will be assigned
default types:
- true/false become Bool
- numbers become Int64
- strings become String
- Bool for literal errors
Column -> the syntax is
#n, where n is the column number.
