Adhoc Errors

A library for the construction of efficient single use static/dynamic error types per callsite.

toml [dependencies] adhocerr = "0.1"

Examples

Creating a root cause error:

```rust use adhocerr::err;

fn getgitroot(start: &Path) -> Result { start .ancestors() .find(|a| a.join(".git").isdir()) .map(Path::toowned) .ok_or(err!("Unable to find .git/ in parent directories")) } ```

Wrapping another Error:

```rust use adhocerr::wrap;

fn recordsuccess() -> Result<(), impl Error + 'static> { std::fs::write(".success", "true").maperr(wrap!("Failed to save results of script")) } ```
