pub struct MirScalarExprDeserializeContext;
Expand description
Extends the test case syntax to support MirScalarExpr
s
The following variants of MirScalarExpr
have non-standard syntax:
Literal -> the syntax is (ok <literal> <scalar type>)
, <literal>
or (err <eval error> <scalar type>)
. Note that 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.
