    derive(Error)

    derive(Error)

    derive(Error) for struct and enum error types

    This is a Rust crate that provides a convenient derive macro (#[derive(Error)]) for implementing std::error::Error on your custom error types (structs or enums). The goal is to enable library authors to build expressive, typed error types, with readable Display implementations (via #[error("...")] annotations) as well as From conversions (#[from]), source tracking (#[source]), and optionally backtraces. It is designed so that switching from handwritten error implementation to using this error is not a breaking change: you retain the same API. ...

    Error Prone

    Error Prone

    Catch common Java mistakes as compile-time errors

    ...Using Error Prone to augment the compiler’s type analysis, you can catch more mistakes before they cost you time, or end up as bugs in production. We use Error Prone in Google’s Java build system to eliminate classes of serious bugs from entering our code, and we’ve open-sourced it, so you can too.

    react-error-boundary

    react-error-boundary

    Simple reusable React error boundary component

    react-error-boundary is a tiny, well-tested utility that makes React’s error boundaries practical and ergonomic for everyday apps. It wraps React’s error-handling primitives in a single <ErrorBoundary> component with a predictable API for rendering fallbacks when descendant components throw during render, lifecycle, or event handlers. The library emphasizes recovery, not just failure: you can reset the error state programmatically or when certain “reset keys” change, returning the subtree to a healthy state without a full page refresh. ...

    Anyhow

    Anyhow

    Flexible concrete Error type built on std::error::Error

    This is a Rust library (crate) that provides a flexible, concrete error type built atop the standard std::error::Error trait. Its primary goal is to make error handling in applications easy: instead of defining lots of custom error types, you can use anyhow::Error (or the alias anyhow::Result<T>) for fallible functions. The crate supports attaching context to errors, so you can convert a low-level error (like “file not found”) into one with richer diagnostics (“Failed to read instructions from path X”) using .context() or .with_context(). ...

    The open source error catcher that's Airbrake API compliant

    ...It is Airbrake API compliant, so if you are already using Airbrake, you can just point the airbrake gem to your Errbit server. The way Errbit arranges notices into error groups is configurable. By default, Errbit uses the notice's error class, error message, complete backtrace, component (or controller), action and environment name to generate a unique fingerprint for every notice. Notices with identical fingerprints appear in the UI as different occurences of the same error and notices with differing fingerprints are displayed as separate errors. ...

    Error propagation calculator and library for physical measurements

    Error propagation calculator and library for physical measurements. It supports real and complex numbers with uncertainty, arbitrary precision calculations, operations with arrays, and numerical integration. Physical measures are typically reported with an error, a quantification of the uncertainty of the accuracy of the measurement. Whenever you perform mathematical operations involving these quantities you have also to propagate the uncertainty, so that the resulting number will also have an attached error to quantify the confidence about its accuracy. ...

    Handle errors in a simple, stable, consistent way. Exporting and documenting all error classes allows consumers to check them. This also enables sharing error classes between modules. Error properties that are internal or secret can be prefixed. This makes them non-enumerable, which prevents iterating or logging them.

    Assertions to validate method input/output with nice error messages

    ...With these assertions, you can greatly reduce the amount of coding needed to write a safe implementation. This library is heavily inspired by Benjamin Eberlei's wonderful assert package, but fixes a usability issue with error messages that can't be fixed there without breaking backwards compatibility. This package features usable error messages by default. However, you can also easily write custom error messages. In beberlei/assert, the ordering of the %s placeholders is different for every assertion. This package, on the contrary, provides consistent placeholder ordering for all assertions. ...

If a torrent hits a disk write error, it will be put into upload mode. This means it will not download anything, but only upload. The assumption is that the write error is caused by a full disk or write permission errors. If the torrent is auto-managed, it will periodically be taken out of the upload mode, trying to write things to the disk again.
