local-rolling-file

注意：此仓库基于 https://github.com/Axcient/rolling-file-rs

具有可自定义滚动条件的滚动文件附加器。包括对日期/时间（每日、每小时、每分钟）和/或大小的内置支持。

日志文件结构（以log为文件夹，以log.log为前缀）

• log.log (一个符号链接始终指向最新的日志文件)
• log.log.yyyymmdd.hhmmss (例如：e.g. log.log.20240520.010101)
• ..

这可以与tracing crate和tracing_appender::non_blocking::NonBlocking结合使用，作为tracing_appender::rolling::RollingFileAppender的替代方案。

示例

use rolling_file::*;
let file_appender = BasicRollingFileAppender::new(
    "./log", // folder
    "log.log", // prefix
    RollingConditionBasic::new().daily(),
    9
).unwrap();

let file_appender = local_rolling_file::RollingFileAppender::new(
        folder,
        "log.log",
        local_rolling_file::RollingConditionBasic::new().daily(),
        3,
    )
    .unwrap();
    let (log_file_writer, guard) = tracing_appender::non_blocking(file_appender);
    let local_time = tracing_subscriber::fmt::time::OffsetTime::new(
        UtcOffset::from_hms(8, 0, 0).unwrap(),
        format_description!("[year]-[month]-[day] [hour]:[minute]:[second].[subsecond digits:6]"),
    );
    let subscriber = tracing_subscriber::Registry::default()
        .with(
            tracing_subscriber::fmt::layer()
                .compact()
                .with_target(false)
                .with_file(true)
                .with_line_number(true)
                .with_ansi(false)
                .with_timer(local_time.clone())
                .with_writer(log_file_writer)
                .with_filter(level),
        )
        .with(
            tracing_subscriber::fmt::layer()
                .compact()
                .with_target(false)
                .with_file(true)
                .with_line_number(true)
                .with_ansi(true)
                .with_timer(local_time)
                .with_filter(level),
        );

    // use that subscriber to process traces emitted after this point
    let _ = tracing::subscriber::set_global_default(subscriber);
    tracing::info!("Logger set up successfully");
