Module fragment_codec 

ID remapping for serialized analyzer fragments.

Global IDs aren’t reproducible across runs, so fragments store local ones: counter IDs (TokenId/TextId) as per-file window offsets (rebased on decode), interned IDs (StrId/PathId) as dictionary indices (re-interned on decode). The ID types’ custom serde consults a thread-local session; inactive means passthrough, and an out-of-window ID errors out so the fragment is treated as non-cacheable.

Structs

DecodeSession

EncodeDicts

Dictionaries produced by an encode session. Stored alongside the encoded payload and used to seed the decode session.

EncodeSession

IdRebase

Rebases decoded local IDs onto a freshly reserved counter range.

IdWindow

Half-open ID window (start, end] matching the pre/post counter values around a single file’s parse + pass1.

Functions

begin_decode

begin_encode

end_decode

end_encode

Ends the encode session and returns the collected dictionaries.
