e2e-protection (v0.4.0)

Profile-first E2E toolkit with a tiny session layer.

• Core: E2eProfile, E2eSession, CounterPolicy
• Feature autosar: provides P11, P22, P44, P7, P4m, P7m

See each profile module’s docs for wire details.

e2e-protection (v0.4.0)

Minimal end-to-end protection toolkit with profile-first API and a small session layer.

• Feature-gated AUTOSAR-like profiles (features = ["autosar"]):
  • P11 (CAN-like): 4-bit counter (0..0xE, 0xF forbidden), CRC-8/SAE-J1850, Data-ID either 16-bit (implicit) or 12-bit nibble-mode (hi-nibble explicit).
  • P22 (CAN/FlexRay-like): 4-bit counter (0..15), DataIDList[16], CRC-8/H2F, no explicit length.

This crate uses the upstream crc crate for checksum calculation as requested.
