tracing_subscriber::fmt() .with_max_level(Level::from_str(&env_log_level).unwrap()) .with_target(false) .init(); Run Code Online (Sandbox Code Playgroud) 注意:我使用的::from_str()不是.parse()因为.with_max_level()是通用的并且需要类型注释。 正如@Finomnis 所建议的,一个功能更丰富的...
tracing_subscriber::fmt() .with_max_level(Level::INFO) // 仅INFO、WARN、ERROR Level的日志会被打印 .init(); 2. 通过环境变量控制 // tracing-subscriber = {version="0.3.18", features=["json", "env-filter"]} tracing_subscriber::fmt::fmt() .with_env_filter(tracing_subscriber::EnvFilter...

Motivation When logs are configured with span events, for example: tracing_subscriber::fmt() .with_max_level(Level::INFO) .with_span_events(FmtSpan::CLOSE) .finish(); A warning is alway...
There are a couple tradeoffs with implementing this warning inEnvFiltervs somewhere else, but I think this is the right choice. The potential downsides are: tracing-subscriberwould have to depend ontracingto access theSTATIC_MAX_LEVELconstant (it presently only depends ontracing-core). However, ...
