For example, it was clear that ideally it should be based on standard Python type hints.

Also, the best approach was to use already existing standards.

So, before even starting to code **FastAPI**, I spent several months studying the specs for OpenAPI, JSON Schema, OAuth2, etc. Understanding their relationship, overlap, and differences.

## Design

    val cleaner = get(root)
    assertFailsWith<SSLPeerUnverifiedException> {
      cleaner.clean(certificates, "hostname")
    }
  }

  /** Returns a chain starting at the leaf certificate and progressing to the root.  */
  private fun chainOfLength(length: Int): List<HeldCertificate> {
    val result = mutableListOf<HeldCertificate>()
    for (i in 1..length) {
      result.add(

	}
	for _, tt := range tests {
		t.Run(tt.want, func(t *testing.T) {
			if got := tt.arn.String(); got != tt.want {
				t.Errorf("ARN.String() = %v, want %v", got, tt.want)
			}
		})
	}
}

func TestNewIAMRoleARN(t *testing.T) {
	type args struct {
		resourceID   string
		serverRegion string
	}
	tests := []struct {
		name    string
		args    args
		want    ARN
		wantErr bool

You can see it directly at: <a href="http://127.0.0.1:8000/openapi.json" class="external-link" target="_blank">http://127.0.0.1:8000/openapi.json</a>.

It will show a JSON starting with something like:

```JSON

        "title": "FastAPI",
        "version": "0.1.0"
    },
    "paths": {
        "/items/": {
            "get": {

	// heuristic value that seems like a good starting size.
	b := bytes.NewBuffer(make([]byte, 0, 128))
	if len(c) == 1 {
		for k, v := range c {
			b.WriteString(`{"`)
			escapeStringJSON(b, k)
			b.WriteString(`":"`)
			escapeStringJSON(b, v)
			b.WriteString(`"}`)
		}
		return b.Bytes(), nil
	}

	sortedKeys := make([]string, 0, len(c))
	for k := range c {
		sortedKeys = append(sortedKeys, k)

Continuing the `panicnil` example, if the module or workspace is updated
to say `go` `1.21`, the program can opt back into the old `panic(nil)`
behavior by including this directive:

	//go:debug panicnil=1

Starting in Go 1.21, the Go toolchain treats a `//go:debug` directive
with an unrecognized GODEBUG setting as an invalid program.
Programs with more than one `//go:debug` line for a given setting
are also treated as invalid.
