color-spantrace

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

Setup

Add the following to your Cargo.toml:

toml [dependencies] color-spantrace = "0.1" tracing = "0.1.13" tracing-error = "0.1.2" tracing-subscriber = "0.2.5"

Setup a tracing subscriber with an ErrorLayer:

```rust use tracingerror::ErrorLayer; use tracingsubscriber::{prelude::*, registry::Registry};

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

Create spans and enter them:

```rust use tracing::instrument; use tracing_error::SpanTrace;

[instrument]

fn foo() -> SpanTrace { SpanTrace::capture() } ```

And finally colorize the SpanTrace:

```rust use tracing_error::SpanTrace;

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

Example

This example is taken from examples/usage.rs:

```rust use tracing::instrument; use tracingerror::{ErrorLayer, SpanTrace}; use tracingsubscriber::{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() } ```

This creates the following output
