Warning: output filename collision appears in both stable and nightly builds. It's slightly more impactful than just a warning. Running cargo +nightly test, cargo test, cargo +nightly test in windows produces a linker error where color-spantrace tries to use eyre's usage.exe, see error 2 below. It's worked around pretty easily with cargo clean, but it's a problem that might get worse as the monorepo effort expands! This patch renames `usage.rs` to `CRATENAME-usage.rs`. Issue #115
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:
[dependencies]
color-spantrace = "0.2"
tracing = "0.1"
tracing-error = "0.2"
tracing-subscriber = "0.3"
Setup a tracing subscriber with an ErrorLayer:
use tracing_error::ErrorLayer;
use tracing_subscriber::{prelude::*, registry::Registry};
Registry::default().with(ErrorLayer::default()).init();
Create spans and enter them:
use tracing::instrument;
use tracing_error::SpanTrace;
#[instrument]
fn foo() -> SpanTrace {
SpanTrace::capture()
}
And finally colorize the SpanTrace:
use tracing_error::SpanTrace;
let span_trace = SpanTrace::capture();
println!("{}", color_spantrace::colorize(&span_trace));
Example
This example is taken from 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()
}
This creates the following output
