NIL

✓ from c_uuid_v7 import NIL

Generate a UUID v7 using the C extension. The UUIDv7 class can be instantiated directly and provides .hex and .bytes properties.

from c_uuid_v7 import UUIDv7 # Generate a single UUID v7 uid = UUIDv7() print(uid) # e.g., 018f3a6e-1b2c-7a3d-8e4f-5a6b7c8d9e0f # Generate as hex string hex_str = uid.hex print(hex_str) # Generate as bytes bytes_val = uid.bytes print(bytes_val)

Debug

Known issues

breakingRequires Python >=3.10; on older Python versions, installing from source may fail or produce errors.

fix

Upgrade to Python 3.10 or later.

affects: 0.0.0 to 0.0.11

gotchaThe library exports only UUIDv7, not a function like 'uuid7()' or 'generate()'. Users may mistakenly try to call uuid7() or import from uuid module.

fix

Use `from c_uuid_v7 import UUIDv7; uid = UUIDv7()`.

affects: all

gotchaGenerated UUIDs are time-ordered but not guaranteed to be strictly monotonic across multiple processes due to clock skew or high concurrency; rely on them for ordering within a single process only.

fix

For cross-process monotonicity, consider using a coordinator or additional sequence counter.
