Overview

Package errs provides utilities for combining multiple errors. This is a simplified version of https://github.com/uber-go/multierr (MIT License), adapted for the Gno programming language with a focus on core functionality and idiomatic usage patterns.

Example usage:

Example
1err1 := doSomething()
2err2 := doSomethingElse()
3if err := errs.Combine(err1, err2); err != nil {
4    return err // Returns combined errors or single error
5}

Functions 2

func Combine 

1func Combine(errs ...error) error
source

Combine merges multiple errors into a single error efficiently. It handles several cases:

  • If all input errors are nil, returns nil
  • If there's exactly one non-nil error, returns that error directly
  • If there are multiple non-nil errors, returns a multiError containing them
  • Flattens any *multiError in the input

func Errors 

1func Errors(err error) []error
source

Errors extracts the underlying errors from an error interface. If the error is a multiError, it returns its contained errors. If the error is nil, returns nil. If the error is a regular error, returns a slice containing just that error.
