I found something weird. first logical plan failed silently on cast. second
is arrow cast acts not consistently on the same inputs. so if I run through
first test
```
[datafusion/expr/src/expr_schema.rs:268] &this_type = Date32
[datafusion/expr/src/expr_schema.rs:269] &cast_to_type = Timestamp(
Nanosecond,
None,
)
[datafusion/expr/src/expr_schema.rs:270] can_cast_types(&this_type,
cast_to_type) = true
```
but if I run second test
```
[datafusion/expr/src/expr_schema.rs:268] &this_type = Date32
[datafusion/expr/src/expr_schema.rs:269] &cast_to_type = Timestamp(
Nanosecond,
None,
)
[datafusion/expr/src/expr_schema.rs:270] can_cast_types(&this_type,
cast_to_type) = false
```
I'm looking what in arrow-rs can cause such non determined behaviuor
