Keys of type binary and ygot.

[hellt]

Hi all,
I have been trying to generate state Go structs (with ygot 0.24.4) for SR Linux and noticed that ygot doesn't support keys of type binary.

F0217 13:43:59.166924   21437 generator.go:376] ERROR Generating GoStruct Code: list /srl_nokia-macsec/macsec/interfaces/interface/mka/state/mka-peer has a binary key -- this is unsupported, list /srl_nokia-system/system/sync/ptp/instance/port-ds-list/neighbor-list has a binary key -- this is unsupported

Unfortunately, binary types are quite common in IETF, and some derived data elements follow IETF, for instance, sync:

  typedef clock-identity-type {
    type binary {
      length "8";
      srl_nokia-ext:output-flavor "hex";
    }
    description
      "Identifies unique entities within a PTP Network.
       The identity is an 8-octet array, constructed according
       to specifications in IEEE Std 1588";
    reference
      "IEEE Std 1588-2019: 5.3.4, 7.5.2.2";
  }

I wonder what made ygot resistance to binary keys, given that they are encoded as base64 string

Binary values are encoded with the base64 encoding scheme (see
[RFC4648], Section 4).

ADD1: some refs

• If key of a list is binary, the generated map has invalid keytype "Binary" #426
• Should Binary be string instead of []byte? #456

Closing this, since the discussion happens in #456
