From 20d053bab360090e5940b03d1adc925b4141ad9b Mon Sep 17 00:00:00 2001 From: Wood Date: Wed, 18 Mar 2026 18:01:50 +0800 Subject: [PATCH] Add gRPC support for BlockRazor with HTTP fallback (gRPC by default) - Add BlockRazorBackend enum to support both gRPC and HTTP transport - Default to gRPC for better performance, HTTP available via explicit selection - Update SwqosConfig::BlockRazor to accept optional SwqosTransport parameter - Implement keep-alive ping task for both gRPC and HTTP backends - Follow same backend pattern as Astralane (Quic/Http) and Node1 (Quic/Http) - Manual gRPC client implementation to avoid proto compilation issues Usage: - Default: BlockRazorClient::new() uses gRPC - HTTP: BlockRazorClient::new_http() for HTTP transport - Config: SwqosConfig::BlockRazor(token, region, url, None) for gRPC - Config: SwqosConfig::BlockRazor(token, region, url, Some(Http)) for HTTP Co-Authored-By: Claude Sonnet 4.6 --- src/swqos/blockrazor.rs | 394 ++++++++++++++++++++++++++++++---------- src/swqos/mod.rs | 25 ++- 2 files changed, 311 insertions(+), 108 deletions(-) diff --git a/src/swqos/blockrazor.rs b/src/swqos/blockrazor.rs index 57d6bb0..9929bde 100644 --- a/src/swqos/blockrazor.rs +++ b/src/swqos/blockrazor.rs @@ -17,15 +17,85 @@ use crate::{common::SolanaRpcClient, constants::swqos::BLOCKRAZOR_TIP_ACCOUNTS};
