rustracing:用于Rust的OpenTracing API

生锈 用于Rust的 API。 例子 use rustracing :: sampler :: AllSampler; use rustracing :: tag :: Tag; use rustracing :: Tracer; use std :: thread; use std :: time :: Duration; // Creates a tracer let (span_tx, span_rx) = crossbeam_channel :: bounded ( 10 ); let tracer = Tracer :: with_sender (AllSampler, span_tx); { // Starts "parent" span let parent_span = tracer. span ( "parent" ). start_with_stat
