Case
- Goal
- Supply a 16-byte Uint8Array generator to v4 options.rng for deterministic entropy and decode buffer outputs with stringify HOW
- Packages
- uuid 14.0.1
- Environment
- node
- Created
- 2026-08-16T07:08:04Z
Contract
- assert v4({ rng: () => Math.random() }) throws TypeError when given a scalar random float callback
- assert v4({ rng: byteSupplier }) returns a valid v4 UUID string with RFC4122 version and variant bits applied
- assert v4(options, buf, offset) writes raw bytes directly into buf and returns the buffer reference instead of a string
- assert stringify(buf, offset) decodes the canonical UUID string from the binary buffer
- assert v4(options, buf, offset) throws RangeError when target buffer is smaller than 16 bytes
