## Current Features for validate
+ This package allows for validation options to occur exchange side e.g.
- Checking for ID in an order cancellation struct.
- Determining the correct withdrawal bank details for a specific exchange.
+ Example Usage below:
```go
// import package
"github.com/thrasher-corp/exchanges/validate"
// define your data structure across potential exchanges
type Critical struct {
ID string
Person string
Banks string
MoneysUSD float64
}
// define validation and add a variadic param
func (supercritcalinfo *Critical) Validate(opt ...validate.Checker) error {
// define base level validation
if supercritcalinfo != nil {
// oh no this is nil, could panic program!
}
// range over potential checks coming from individual packages
var errs common.Errors
for _, o := range opt {
err := o.Check()
if err != nil {
errs = append(errs, err)
}
}
if errs != nil {
return errs
}
return nil
}
// define an exchange or package level check that returns a validate.Checker
// interface
func (supercritcalinfo *Critical) PleaseDontSendMoneyToParents() validate.Checker {
return validate.Check(func() error {
if supercritcalinfo.Person == "Mother Dearest" ||
supercritcalinfo.Person == "Father Dearest" {
return errors.New("nope")
}
return nil
})
}
// Now in the package all you have to do is add in your options or not...
d := Critical{Person: "Mother Dearest", MoneysUSD: 1337.30}
// This should not error
err := d.Validate()
if err != nil {
return err
}
// This should error
err := d.Validate(d.PleaseDontSendMoneyToParents())
if err != nil {
return err
}
```
