kandi X-RAY | ffjson Summary

ffjson is a Go library typically used in Utilities, JSON Processing applications. ffjson has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

ffjson generates static MarshalJSON and UnmarshalJSON functions for structures in Go. The generated functions reduce the reliance upon runtime reflection to do serialization and are generally 2 to 3 times faster. In cases where ffjson doesn't understand a Type involved, it falls back to encoding/json, meaning it is a safe drop in replacement. By using ffjson your JSON serialization just gets faster with no additional code changes. When you change your struct, you will need to run ffjson again (or make it part of your build tools).

            Your UnmarshalJSON function calls itself recursively, which will cause the stack to explode in size.
