From 3ece63b64e192146fcdd1724e25856a93d7626aa Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Wed, 22 Sep 2021 13:56:01 -0700 Subject: [PATCH] Temporarily rename int_roundings functions to avoid conflicts These functions are unstable, but because they're inherent they still introduce conflicts with stable trait functions in crates. Temporarily rename them to fix these conflicts, until we can resolve those conflicts in a better way. --- library/core/src/num/int_macros.rs | 38 +++++++++++++-------------- library/core/src/num/uint_macros.rs | 14 +++++----- library/core/tests/num/int_macros.rs | 34 ++++++++++++------------ library/core/tests/num/uint_macros.rs | 10 +++---- 4 files changed, 48 insertions(+), 48 deletions(-) diff --git a/library/core/src/num/int_macros.rs b/library/core/src/num/int_macros.rs index 2a02545041dcf..daef5c98967cc 100644 --- a/library/core/src/num/int_macros.rs +++ b/library/core/src/num/int_macros.rs @@ -1849,17 +1849,17 @@ macro_rules!
