Crate

anyhow

Flexible error handling and propagation for Rust applications.

What it is

anyhow provides a single anyhow::Error type that wraps any error value. Errors gain context with .context("...") and propagate across heterogeneous error types via the ? operator without needing explicit From conversions.

Why it is commonly used

Standard in Rust application code rather than libraries. When callers do not need to inspect the error type — scripts, binaries, tools — anyhow eliminates error-handling boilerplate without sacrificing meaningful messages.

Crates that show up unusually often in anyhow projects. The most distinctive pairings rank first — crates these projects use far more than the average indexed Rust project does, not just crates that are popular everywhere. Each percentage is the share of anyhow projects that also use it.
