Some JSON Schema keywords, like minLength, are logically integers.
The JSON Schema spec allows them to be written as floating-point
values with zero fractional part, which is a reasonable choice, since
JSON doesn't distinguish the two.
We could simply validate these fields as integers in the normal course
of events (namely, validating the schema against its meta-schema),
but this CL does a little better: it uses *int struct fields for
these keywords, preventing them from ever being non-integers.
The UnmarshalJSON method still accepts integral floating-point values.
Marshaling is unaffected, and the results don't change: encoding/json
has always marshaled integral floats without the decimal part.
Other choices:
- Leave them as float64: you could then get away with
Schema{MinLength: Ptr(1.5)}
and though you couldn't get far with that, it's still irksome.
- json.Number: same problem as float64, plus it's even harder to write
as a literal.
- int64: now `Ptr(1)` doesn't work (it's a *int, not a *int64).
Anyway, these keywords all compare against len(x) in Go, which
is of type int.
