SafeConversion provides safe type casting functions for Go.
go get github.com/corentings/safeconversionimport "github.com/corentings/safeconversion"CastInt provides a safe way to cast an integer from one type to another.
func CastInt[From, To safeconversion.Integer](value From) (To, error)result, err := safeconversion.CastInt[int32, int64](math.MaxInt32)
// result is 9223372036854775807 and err is nil
result, err = safeconversion.CastInt[int64, int32](math.MaxInt64)
// result is 0 and err is safeconversion.ErrValueOutOfRange- TODO

This library is not meant to replace the standard type casting functions. It is meant to provide a safe alternative when the standard functions would silently overflow or underflow. It's not recommended to use this library without auditing the code first to be sure it fulfills your needs.
I am not a security expert, so use this library at your own risk.
