help: you are looking for the module in `std`, not the primitive type
|
325 | if shiftee_bits <= std::u8::MAX as usize {
| ^^^^^^^^^^^^
what am I doing wrong?
Chris Fallin (Jul 20 2020 at 18:29):Hmm, that's from my recent commit... are you building no_std? What version is your rustc?
Chris Fallin (Jul 20 2020 at 18:31):(It looks like the fix is just as rustc says there; I can do a quick PR for that; but I'm curious how this arose)
Carlo Kok (Jul 20 2020 at 18:32):trying an update to rustc 1.45.0 (5c1f21c3b 2020-07-13) now actually, was a few months behind
Carlo Kok (Jul 20 2020 at 18:32):unfortunately, I didn't note what rust version I did have :(
Chris Fallin (Jul 20 2020 at 18:33):A quick grep shows a number of other unqualified u32::MAX, etc., but I'm happy to fix this one if it broke some build configuration...
Carlo Kok (Jul 20 2020 at 18:35):no need for me (presuming the update fixes it)
Chris Fallin (Jul 20 2020 at 18:35):Oh, interesting, as per https://doc.rust-lang.org/std/primitive.u8.html the u8::MAX member (for primitive u8) is only stable in 1.43
Chris Fallin (Jul 20 2020 at 18:36):We try to support 1.41; so I'll go ahead and fix this. Thanks!
Carlo Kok (Jul 20 2020 at 18:37):damn; I accidentally selected a char in the console; so was waiting indefinitely for rust/windows to finish building (selection blocks stdout, which pauses rust)
Chris Fallin (Jul 20 2020 at 18:38):Created https://github.com/bytecodealliance/wasmtime/pull/2047
Carlo Kok (Jul 20 2020 at 18:38):you are fast.
Chris Fallin (Jul 20 2020 at 18:41):rustc told me exactly what to do :-)
Carlo Kok (Jul 20 2020 at 18:42):;0
