Open /dev/kmsg in Android am: 39bcfd940e am: 07eb49bf51 am: b4a3b70f23 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/kernlog/+/1747976 Change-Id: Ifcd8f06cc2b2364464c8fd75a879073ec835f30d
Logger implementation for low level kernel log (using /dev/kmsg)
Usually intended for low level implementations, like systemd generators, which have to use /dev/kmsg:
Since syslog is not available (see above) write log messages to /dev/kmsg instead.
[dependencies] log = "0.4" kernlog = "0.3"
#[macro_use] extern crate log; extern crate kernlog; fn main() { kernlog::init().unwrap(); warn!("something strange happened"); }
Note you have to have permissions to write to /dev/kmsg, which normal users (not root) usually don't.
