Objective
Since Rust 1.77,
round_ties_even
was added tof32
andf64
in the standard library. This function is used within WGPU, and as a part of a push forno_std
support, this function will need to be shimmed. It could be shimmed within Naga, but this functionality may have value to other users ofnum-traits
.Solution
round_ties_even
toFloatCore
,Float
, andReal
with a default implementation (not a breaking change)has_round_ties_even
configuration check to allow detectinground_ties_even
provided by the standard library in Rust 1.77 and above (not a breaking change)round_ties_even
matches the implementation instd
for thef32
type (assuming it is equally valid forf64
)Notes
TheResolved usingmsrv_1_77
feature increases MSRV to 1.77, which is a typical arrangement (e.g.,serde
features will typically elevate MSRV). If/whennum-traits
advances past MSRV 1.77, this feature can become a no-op without any breaking changes.build.rs
andautocfg
.num-traits
