Crate tidepool_server 

Tidepool HTTP + WebSocket JSON-RPC server. Wraps the service layer’s async functions behind an axum front-end.

Public surface:

• run starts the server and blocks until shutdown.
• ServerConfig holds port, upstream URL, and optional indexed trees.
• HttpUpstream is the production UpstreamClient impl; consumers building their own servers can import it directly.

Re-exports

Modules

config

Server configuration. Shape mirrors the TS ProxyOptions plus server-specific knobs (port, WS URL override).

dispatcher

JSON-RPC method dispatch. The core architectural win: every method we serve maps to a Method enum variant, and the dispatch function does an exhaustive match. Adding a new method = add a variant + a match arm; compiler fails the build if you forget.

http

axum HTTP server: JSON-RPC over POST, CORS, passthrough proxy for anything the dispatcher doesn’t claim.

json_rpc

JSON-RPC 2.0 envelope types. Kept minimal + lenient — Solana’s RPC ecosystem varies slightly between 1.0 / 2.0 implementations and we want to pass through whatever clients send without over- validating.

rest

REST transport. Mirrors the paths helius-sdk hits on api.helius.xyz/v0/... — served from the same base URL as our JSON-RPC endpoint so a user pointing helius-sdk at Tidepool gets every method, on the transport the SDK expects.

upstream_http

Production UpstreamClient impl over reqwest. Plain JSON-RPC POST to the upstream URL.

webhook_runtime

Per-process webhook runtime: registry + background delivery tasks.

ws

WebSocket server with polling-based subscription polyfills.

Traits

UpstreamClient

An abstract Solana RPC client. rpc_call is the catch-all; typed conveniences sit on top of it where we care about ergonomics.
