func Assign ¶
Assign wraps function call returning a `val` and error to log it if error != nil using `log/slog` so it has `msg` and `log`. example:
file := Assign(os.Create("log.txt"),
"Can not create file",
"file", "log.txt"
)

type Result ¶ added in v0.0.3
type Result[T, E any] interface { Error() E Value() T Failure() bool Success() bool Map(func(T) any) Result[any, E] FlatMap(func(T) Result[T, E]) Result[T, E] Or(ErrorHandler[T, E]) Result[T, E] }
Result represents a result of an operation that can fail
