checker — generic validators
import "github.com/downsized-devs/sdk-go/checker"
Stability: Stable — see STABILITY.md
Tiny library of validation helpers. Uses generics; no external deps.
Features
ArrayInt64Contains,ArrayContains— membership tests.ArrayDeduplicate— remove duplicates while preserving order.IsEmail,IsPhoneNumber— regex-based format checks.
Installation
go get github.com/downsized-devs/sdk-go/checker
Quick Start
import "github.com/downsized-devs/sdk-go/checker"
ok := checker.ArrayContains([]string{"a", "b"}, "a") // true
clean := checker.ArrayDeduplicate([]int{1, 1, 2}) // [1, 2]
checker.IsEmail("alice@example.com") // true
