color-spantrace

A rust library for colorizing tracing_error::SpanTrace objects in the style of color-backtrace.

设置

将以下内容添加到您的 Cargo.toml

[dependencies]
color-spantrace = "0.2"
tracing = "0.1"
tracing-error = "0.2"
tracing-subscriber = "0.3"

使用 ErrorLayer 设置跟踪订阅者

use tracing_error::ErrorLayer;
use tracing_subscriber::{prelude::*, registry::Registry};

Registry::default().with(ErrorLayer::default()).init();

创建跨度并进入它们

use tracing::instrument;
use tracing_error::SpanTrace;

#[instrument]
fn foo() -> SpanTrace {
    SpanTrace::capture()
}

最后，为 SpanTrace 着色

use tracing_error::SpanTrace;

let span_trace = SpanTrace::capture();
println!("{}", color_spantrace::colorize(&span_trace));

示例

此示例取自 examples/color-spantrace-usage.rs

use tracing::instrument;
use tracing_error::{ErrorLayer, SpanTrace};
use tracing_subscriber::{prelude::*, registry::Registry};

#[instrument]
fn main() {
    Registry::default().with(ErrorLayer::default()).init();

    let span_trace = one(42);
    println!("{}", color_spantrace::colorize(&span_trace));
}

#[instrument]
fn one(i: u32) -> SpanTrace {
    two()
}

#[instrument]
fn two() -> SpanTrace {
    SpanTrace::capture()
}

这将产生以下输出
