Bug Report

Version

Platform

Windows (64-bit)

Crates

async-trait v0.1.35

Description

When adding #[tracing::instrument] to a function in a #[async_trait::async_trait] trait implementation, include_str will think its in the root of the src folder when its not.

File tree:

src/
+-- lib.rs
+-- example/
    +-- mod.rs
    +-- text.txt

lib.rs:

mod example;

#[async_trait::async_trait]
pub trait Test {
    async fn example(&self);
}

mod.rs:

use crate::Test;

#[derive(Debug)]
pub struct Example {}


#[async_trait::async_trait]
impl Test for Example {
    #[tracing::instrument]
    async fn example(&self) {
        let _text = include_str!("text.txt");
    }
}
