From 82b3a3ca6ab2b50b20210f05f19a9b8a6886241c Mon Sep 17 00:00:00 2001 From: eareimu Date: Thu, 23 Apr 2026 16:38:53 +0800 Subject: [PATCH 001/318] refactor(endpoint): rename Bind to BindPattern and flatten Identity - rename Bind -> BindPattern to avoid ambiguity with binding operations - replace Identity enum with plain struct; endpoints now hold Option> (None = anonymous client-only) - wrap QuicEndpoint client/server configs in Arc; add *_mut() helpers using Arc::make_mut for copy-on-write mutation - wrap H3Endpoint.quic in Arc; add quic_mut() helper - add Hash impls for BindHost and BindPattern - add Endpoint alias for H3Endpoint - add H3Endpoint::connect/get/post convenience client methods - update network, sni, tests accordingly --- src/endpoint/binds/collection.rs | 14 +- src/endpoint/binds/error.rs | 2 +- src/endpoint/binds/host.rs | 25 +- src/endpoint/binds/mod.rs | 2 +- src/endpoint/binds/pattern.rs | 48 ++-- src/endpoint/binds/tests.rs | 110 ++++---- src/endpoint/config.rs | 24 ++ src/endpoint/h3.rs | 66 ++++- src/endpoint/identity.rs | 58 +--- src/endpoint/mod.rs | 8 +- src/endpoint/network.rs | 448 +++++++++++++++++-------------- src/endpoint/quic.rs | 72 +++-- src/endpoint/sni.rs | 4 +- tests/endpoint.rs | 128 +++++++-- 14 files changed, 605 insertions(+), 404 deletions(-) diff --git a/src/endpoint/binds/collection.rs b/src/endpoint/binds/collection.rs index 3fc6e8c..bcd3efa 100644 --- a/src/endpoint/binds/collection.rs +++ b/src/endpoint/binds/collection.rs @@ -6,23 +6,23 @@ use std::{ use derive_more::{Deref, DerefMut, From, Into};
