Crate yapi_types 

Serde types for pi’s JSON formats: messages, events, session entries, settings, models and extension payloads.

A pi file is handled as a document: an order-preserving serde_json::Value that json writes back byte-identically. pi’s key order depends on the code path that built an object, so the typed structs here are views: they read fields from a document and build new objects in pi’s usual key order.

Modules

auth

auth.json: stored credentials keyed by provider id.

autocomplete

pi-tui’s autocomplete shapes, as extensions’ providers and command argument completions exchange them; packages/tui/src/autocomplete.ts in pi v1.0.0.

classify

Classifier and image-generation requests and results.

collate

String ordering as JavaScript’s localeCompare gives it for identifiers and file names.

config

pi’s JSON configuration files and how pi lays each one out on disk.

event

Streaming events, in the shape pi’s JSON and RPC modes print them.

extension_event

Events pi delivers to extension handlers, in the shape and key order of pi’s emit sites.

js

JavaScript string and number semantics that pi’s texts depend on: string lengths and slices count UTF-16 code units, and toFixed and Math.round round halves up.

json

JSON output that matches pi’s JSON.stringify.

message

Messages stored in sessions and sent to providers.

model

Catalog models: what a provider serves and how to talk to it.

models

models.json: custom providers, models and overrides.

rpc

RPC mode: commands read from stdin and the responses written to stdout, as in modes/rpc/rpc-types.ts of pi v1.0.0. Events use the JSON mode shapes in crate::event.

session

Lines of a session file: one header, then entries forming a tree.

settings

settings.json, global and project scope.

sync

Locking that outlives a panic.

system_prompt

pi’s system prompt inputs, as before_agent_start hands them to extensions.

time

Timestamps as pi writes them: Unix milliseconds and ISO 8601 UTC with milliseconds, and ids.
