Hardcoded random ID generator — the only generator this SDK ships.

Generates non-zero random integers using :rand.uniform/1:

• trace_id: 128-bit (1 to 2^128 - 1)
• span_id: 64-bit (1 to 2^64 - 1)

Spec ref: trace/sdk.md §IdGenerator. The behaviour abstraction (and a separate Default impl module) was collapsed because the SDK ships only this generator and users cannot substitute their own (per minikube-style scope).

Public API

Deferred Development-status features

• Random TraceFlag bit. Spec trace/api.md L237-L242 defines bit 1 (0x02) of the W3C trace-flags byte as the Random flag, set when the IdGenerator produces trace IDs whose lower 7 bytes are random. Spec trace/sdk.md L902-L912 "IdGenerator randomness" (Status: Development) describes the SDK's responsibility to declare this property. Not implemented — span.ex currently sets only the Sampled bit (0x01) on the in-memory trace_flags. When stabilised, this module will gain a method describing its randomness profile and span.ex will set bit 1 accordingly.
