-1 from me for Rust in the kernel, +1 for Rust in apps. Sebastien and Tomek gave enough arguments to avoid Rust in the kernel.
Not a technical argument from me: Rust has too many arrogant members in the community with a messianic approach (like `Rust will save embedded, blah, blah, blah`), it's quite irritating and bad for your mental health :) czw., 14 mar 2024 o 00:36 Tomek CEDRO <to...@cedro.info> napisał(a): > On Wed, Mar 13, 2024 at 10:03 PM Gregory Nutt wrote: > > On 3/13/2024 2:42 PM, Tomek CEDRO wrote: > > > You want Rust in the core go ahead write RustOS have fun maintaining > it for 5 years and show us its better :-) > > > > You are probably right in that.
