From 6dcbb5ce41a52b8f01b32fac395acc98d2fe17de Mon Sep 17 00:00:00 2001 From: Matt Corallo Date: Tue, 11 Jul 2023 02:00:22 +0000 Subject: [PATCH] Drop `ScoreParams` in bindings builds Sadly, we can't realistically expose associated types in bindings - not only does C not have any concept of generics or associated types (duh), but many of the downstream languages we support don't either. Instead, we hard-code the scoring parameters type to `ProbabilisticScoringFeeParams` for all scorers. --- lightning-background-processor/src/lib.rs | 20 ++- lightning/src/ln/channelmanager.rs | 16 +- lightning/src/ln/functional_test_utils.rs | 4 +- lightning/src/ln/functional_tests.rs | 10 +- lightning/src/ln/onion_route_tests.rs | 2 +- lightning/src/ln/payment_tests.rs | 6 +- lightning/src/ln/peer_handler.rs | 7 +- lightning/src/ln/shutdown_tests.rs | 4 +- lightning/src/routing/router.rs | 170 +++++++++++----------- lightning/src/routing/scoring.rs | 7 + lightning/src/util/test_utils.rs | 7 +- 11 files changed, 144 insertions(+), 109 deletions(-) diff --git a/lightning-background-processor/src/lib.rs b/lightning-background-processor/src/lib.rs index 1ed6a2a83..586fac930 100644 --- a/lightning-background-processor/src/lib.rs +++ b/lightning-background-processor/src/lib.rs @@ -885,6 +885,7 @@ mod tests { fn disconnect_socket(&mut self) {} } + #[cfg(not(c_bindings))] type ChannelManager = channelmanager::ChannelManager< Arc, @@ -901,6 +902,22 @@ mod tests { TestScorer> >, Arc>;
