My laptop is armv7 linux, and not being able to run rustc on it has been annoying. Well, I did find some binary of some old version somewhere, but it's of limited usefulness since it's old, and it didn't come with cargo, which also wants to bootstrap itself from a native binary. The last time I tried it, I couldn't even cross-compile an ARM rustc from x86_64, because the build scripts wanted to run the binary they were building. This is literally the only reason I've been using C and not Rust (which would have been a much more suitable language) for my latest project.

EDIT: Huh. I guess they do have binaries for arm linux now, at least for nightly and beta versions, as of literally two days ago.

Maybe not on Android but on GNU/Linux on something other than x86/x86_64 sure.

Having just acquired a pixel c tablet, I am increasingly looking forward to being able to iterate on my rust projects while being highly mobile. I don't see it as a primary development platform in the near future, but absolutely invaluable as an auxiliary one.

The last time I checked android compiling looked very complicated, tons of steps, tool chain setup for Windows. I hope one day it's as simple as flagging the build for the specified architecture.
