Function trace_tools::subscriber::collect_logs

pub fn collect_logs() -> Result<(), SetLoggerError>

Initialises a tracing_log::LogTracer that converts any incoming log records into tracing events, allowing subscribers to interact with log records.

This is necessary to perform logging through the log crate whilst also setting the global logger to a tracing::Subscriber implementation.

Errors

• Returns an Error if this function has failed to set the global logger.

Notes

• This should only be called once. Any subsequent calls will fail, since the global logger can only be set once in a program’s lifespan.
• If the global logger has already been set (by the log crate, for example), this will fail.
