From 8bf2725f9be82eec0849cc5efe77bedeb0a693a0 Mon Sep 17 00:00:00 2001 From: Jeffery To Date: Sat, 30 Sep 2023 13:57:43 +0800 Subject: [PATCH] rust: Set release profile settings * codegen-units, lto, opt-level - Set to values to optimize binary size[1]. * overflow-checks - Enabled because in release mode, integer overflows are defined as two's complement wrap[2]. It is highly unlikely that any program is intentionally relying on this behaviour; it would be better to panic instead of continue execution in this case. * debug, debug-assertions, panic, rpath - Set to their default (release) values, to override any settings made by packages, e.g. ripgrep sets debug = 1[3].
