The total number of rejected pull requests for this library's source code repository on GitHub.

Closing a pull request without merging the associated source code changes can have many reasons:

• the proposed change might have been solved in a different PR
• the project maintainers considered a proposed change out of scope for the library
• the submitter of the PR may have lost interest and the PR has become stale
• the proposed change may not have met the quality standards of the project

In general, a high number of closed pull requests often indicates that a library has a large community and incoming change proposals are considered and responded to by the maintainers.
