Function truncateForMsg

encoding_json_fuzz_test.go:127–133

truncateForMsg renders a byte slice for inclusion in an error message, truncating very large inputs (e.g. the 100 KB deep-nesting seed) so test output remains readable.

(b []byte)

// truncating very large inputs (e.g. the 100 KB deep-nesting seed) so test
// output remains readable.
func truncateForMsg(b []byte) string {
	const max = 200
	if len(b) <= max {
		return fmt.Sprintf("%q", b)
	}
	return fmt.Sprintf("%q...(truncated, %d bytes total)", b[:max], len(b))
}

// genDeepNesting returns deeply-nested JSON array bytes. When closed is true
// the structure is complete ([[[...1...]]]); when false it is left unclosed
