[pbs-devel] [PATCH proxmox 1/2] proxmox-log: added tracing infra

Gabriel Goller g.goller at proxmox.com
Fri Nov 3 12:28:48 CET 2023


Added the `proxmox_log` crate which includes the new logging infra.
Exports the `init_logger` function, which creates the `tracing` logger
that includes the default Subscriber and a single layer. The layer
checks if a `tokio::task_local!` variable is set, if it is,
it logs to the tasklog using the `FileLogger`. If it isn't, the message
goes to syslog (using the `syslog` crate).
