Struct tracing_tree::HierarchicalLayer [−][src]
pub struct HierarchicalLayer<W = fn() -> Stdout> where
W: MakeWriter + 'static, { /* fields omitted */ }
Implementations
pub fn with_writer<W2>(self, make_writer: W2) -> HierarchicalLayer<W2> where
W2: MakeWriter + 'static,
Renders an ascii art tree instead of just using whitespace indentation.
Whether to render the event and span targets. Usually targets are the module path to the event/span macro invocation.
Whether to render the thread id in the beginning of every line. This is helpful to untangle the tracing statements emitted by each thread.
Whether to render the thread name in the beginning of every line. Not all threads have names, but if they do, this may be more helpful than the generic thread ids.
Resets the indentation to zero after wraparound
indentation levels.
This is helpful if you expect very deeply nested spans as otherwise the indentation
just runs out of your screen.
Whether to print the currently active span’s message again before entering a new span. This helps if the entry to the current span was quite a while back (and with scrolling upwards in logs).
Whether to print the currently active span’s message again before dropping it. This helps if the entry to the current span was quite a while back (and with scrolling upwards in logs).
Whether to print {}
around the fields when printing a span.
This can help visually distinguish fields from the rest of the message.
