Clarify on relationship between FilterBuilder and max-level

[pronebird]

Hi,

Could you please clarify why do we need max_level and filter at the same time? I understand that we can set the log level for individual crates but how does debug, in the filter string affects the max level that we set? (trace)

android_logger::init_once(
        Config::default()
            .with_max_level(LevelFilter::Trace)
            .with_tag("mytag")
            .with_filter(FilterBuilder::new().parse("debug,hello::crate=trace").build()),
    );
