README

giouring - about the project

giouring is a Go port of the liburing library. It is written entirely in Go. No cgo.

Almost all functions and structures from liburing was implemented.

The giouring API is very similar to the liburing API, so anyone familiar with liburing will find it easier when writing code. Significant changes include:

  • Method and structure names have been aligned with the naming conventions of the Go language.
  • The prefix io_uring has been removed from method and structure names. After importing the package, methods and types will be preceded by the library name: giouring.
  • SQE and CQE types have been given full names: SubmissionQueueEntry and CompletionQueueEvent.
  • Additionally, if a method primarily pertains to a specific structure, for example, all methods prefixed with io_uring_prep that are related to the SubmissionQueueEntry structure (in liburing: io_uring_sqe), the pointer that was passed in C as a method argument has been moved to the method receiver.
Important notice
  • giouring was tested on kernel version 6.2.0-27-generic. Keep in mind that when running unit tests on older kernel versions, some tests may fail because the older kernel may not support some functionality. This will be fixed in the future.
  • Test coverage is currently low, but it will be systematically expanded.
