Enum SessionFormat 

pub enum SessionFormat {
    ClaudeCode,
    Codex,
    OpenCode,
    Pi,
    Grok,
    Gemini,
    Goose,
}

An on-disk session format supercode can both read and write.

Like an image editor that opens and exports several file formats, supercode keeps one canonical in-memory model (Session) and converts to/from each supported format on the edges.

This is a write-target / codec selector: a caller’s request, passed to Session::load_str, Session::to_jsonl, and Session::save, choosing which on-disk dialect to parse or emit. It answers “what format should I read/write?” — as opposed to SessionSource, which records the provenance fact of what actually produced a loaded file. The two enums are intentionally kept separate (provenance fact vs. serialization choice) and should not be unified, even though their variants currently match one-to-one.

Implementations

impl SessionFormat

pub fn source(self) -> SessionSource

The SessionSource a file of this format reports.

This is the deliberate one-way bridge between the two concepts: a file saved in this format will, when reloaded, report this provenance (see crates/harness/tests/session_saving.rs), making the relationship discoverable from the method itself.
