Std.Validate.about
1 declaration
fn
about: Str -> Str -> fn(Map[Str, Str]) -> Bool -> &Map[Str, Str] -> Std.Validate.ReportThis is a callable function.
What it does
A rule over the whole form rather than one field, for a check that needs
more than one value.
Written this way rather than by letting a field's rule name another field:
a reference makes the order fields are checked in significant, and then a
report depends on a declaration order nobody thought was load-bearing.
Read the signature
- The text after the name is the type checked by Pudu.
- Read arrows from left to right: inputs come first, and the final type is returned.
- & borrows a value for this call instead of moving or copying it.
- Names inside [ ] are type arguments, such as the item type held by a collection.
