+# stringish
+
+A small Go module that provides a generic type constraint for “string-like”
+data, and a utf8 package that works with both strings and byte slices
+without conversions.
+
+```go
+type Interface interface {
+	~[]byte | ~string
+}
+```
+
+[![Go Reference](https://pkg.go.dev/badge/github.com/clipperhouse/stringish/utf8.svg)](https://pkg.go.dev/github.com/clipperhouse/stringish/utf8)
+[![Test Status](https://github.com/clipperhouse/stringish/actions/workflows/gotest.yml/badge.svg)](https://github.com/clipperhouse/stringish/actions/workflows/gotest.yml)
+
+## Install
+
+```
+go get github.com/clipperhouse/stringish
+```
+
+## Examples
+
+```go
+import (
+    "github.com/clipperhouse/stringish"
+    "github.com/clipperhouse/stringish/utf8"
+)
+
+s := "Hello, 世界"
+r, size := utf8.DecodeRune(s)   // not DecodeRuneInString 🎉
+
+b := []byte("Hello, 世界")
+r, size = utf8.DecodeRune(b)    // same API!
+
+func MyFoo[T stringish.Interface](s T) T {
+    // pass a string or a []byte
+    // iterate, slice, transform, whatever
+}
+```
+
+## Motivation
+
+Sometimes we want APIs to accept `string` or `[]byte` without having to convert
+between those types. That conversion usually allocates!
+
+By implementing with `stringish.Interface`, we can have a single API, and
+single implementation for both types: one `Foo` instead of `Foo` and
+`FooString`.
+
+We have converted the
+[`unicode/utf8` package](https://github.com/clipperhouse/stringish/blob/main/utf8/utf8.go)
+as an example -- note the absence of`*InString` funcs. We might look at `x/text`
+next.
