Module socket_transport 

SocketTransport — the client side of the daemon UDS (PLAN-phase2 §2.10).

Line-JSON frames (wire.rs). A writer task owns the write half; the reader lives on the transport. Backpressure mirrors LocalTransport: send fails with Backpressure when the bounded writer queue is full and Closed once the socket is gone — never a silent drop.

Tracing here logs frame types only (ClientFrame’s redacting Debug).

Re-exports

pub use crate::extensions::manager::ExtensionReloadReport;

Structs

Connected

A connection past Hello/Welcome, before Attach.

ExtensionReloadFailure

The daemon’s reason an extension was not reloaded (DaemonFrame::ExtensionReloadFailed).

FrameBuf

Reused line buffer for read_frame: a big Attached/MessageHistory frame grows it once; after any frame > 1 MiB it shrinks back to 64 KiB so the peak is not retained for the life of the connection (§2.1 #1).

Enums

AuthStateReply

What synaps auth state got from the daemon.

Constants

CLOSE_TIMEOUT

How long close waits for the daemon’s answer: its queue retry, the actor’s reply and the session’s end (daemon/close.rs budgets), plus a margin.

CONNECT_TIMEOUT

HANDSHAKE_TIMEOUT

PIN_TIMEOUT

How long pin waits for the daemon’s answer: its longest wait (a parked session unparking) plus a margin.

RELOAD_EXTENSION_TIMEOUT

How long reload_extension waits: the daemon first waits for the extension manager’s lock, then stops the old process and runs the new one’s start-up handshake (each bounded by the extension runtime’s own timeouts, around 15 s together). Generous, because giving up early only hides the answer: the daemon finishes the reload either way.

Functions

predates_auth_state

An old daemon’s reply to AuthState (daemon/conn.rs Read::Bad: serde’s unknown-variant error behind “malformed frame: “), and nothing else.
