Function initializeLogger

Initialize the logger used by @wasmer/wasix.

This function can only be called once. Subsequent calls will raise an exception.

Filtering Logs

The filter string can be used to tweak logging verbosity, both globally or on a per-module basis, and follows the $RUST_LOG format.

Some examples:

• off - turn off all logs
• error, warn, info, debug, trace - set the global log level
• wasmer_wasix - enable logs for wasmer_wasix
• info,wasmer_js::package_loader=trace - set the global log level to info and set wasmer_js::package_loader to trace
• wasmer_js=debug/flush - turns on debug logging for wasmer_js where the log message includes flush
• warn,wasmer=info,wasmer_wasix::syscalls::wasi=trace - directives can be mixed arbitrarily

When no filter string is provided, a useful default will be used.
