Trait IoResultExt 

pub trait IoResultExt<T> {
    // Required method
    fn with_path(self, path: impl Into<PathBuf>) -> Result<T>;
}

Extension trait for ergonomic conversion of io::Result<T> into the crate’s path-bearing Result<T>. Reads at call sites as std::fs::read_to_string(&path).with_path(&path)? — one extra token compared to .map_err(Error::Io)?, with much better diagnostics on failure.

Required Methods

fn with_path(self, path: impl Into<PathBuf>) -> Result<T>

Wrap an io::Error with the path that produced it, returning an Error::IoAt on failure.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
