TODO
At current moment strulidator isn't ready for production. If you want to help me with release please read the first issue.
Reference
type Validator = (value: any) => boolean
type Constraint = (value: any) => ConstraintResult
type ConstraintResult = {
valid: boolean,
message: string | void,
children: ConstraintResultMap | ConstraintResultArray | void
}
type ConstraintResultMap = {
[key: string]: ConstraintResult
}
type ConstraintResultArray = Array<ConstraintResult>Usage
