Struct MakeConsoleWriter

pub struct MakeConsoleWriter(/* private fields */);

This is the main type that is passed to with_writer.

Note that you can map the tracing levels to different console verbosity levels. This is especially useful for mapping tracing::Level::TRACE to a different console level, such as debug, to avoid all trace tracing events showing up in the browser’s console with their backtrace expanded.
