Types ¶
type Result ¶
type Result[T any] struct { // contains filtered or unexported fields }
A Result type is a type that can contain an error or a value.
func From ¶ added in v0.14.0
From returns a Result that contains a value or an error.
It can be used to convert a function that returns a value and an error into a Result.
func Map ¶ added in v0.20.0
Map a Result[L] to Result[R]. If Result[L] is an error mapper will not be called and the result will be an error.
func (Result[T]) Default ¶
func (r Result[T]) Default(value T) T
Default returns the Result value if it is present, otherwise it returns the value passed.
func (Result[T]) MarshalJSON ¶
func (*Result[T]) UnmarshalJSON ¶
