# lerror
Another rust error crate. 

Report file name, line and column instead of backtrace.

Most code is copied from `anyhow`.

# Usage
```rust
use lerror::{bail, Context, ContextExt, Result};

#[test]
fn a() -> Result<()> {
    b().c()?;  // You need to call `c()` to add the current line to backtrace without context. Or you can call `context()` to add string context.
    bail!("permission denied for accessing {}", "resource");
    Ok(())
}

fn b() -> Result<()> {
    c().context("File not found")?;
    bail!("File not found");
}

fn c() -> Result<()> {
    bail!("Image not found");
}
```

Output:

```
Error: lerror::Error

       File not found
