func Must ¶

func Must[T any](v T, err error) T

Used to apply the Must pattern to any function returning a value and an error:

Usage: x := Must(functionReturningOneValueAndAnError())
If there is no error the return value is returned and stored into 'x'.
If there is an error it will be logged using `logging.LogGoErrorFatal(err)` which aborts the execution.

func Must0 ¶

func Must0(err error)

Same as `Must` but for functions only returning an error.

func Must2 ¶

func Must2[T1 any, T2 any](v1 T1, v2 T2, err error) (T1, T2)

Same as `Must` but supporting 2 return values.

func Must3 ¶

func Must3[T1 any, T2 any, T3 any](v1 T1, v2 T2, v3 T3, err error) (T1, T2, T3)

Same as `Must` but supporting 3 return values.

func Must4 ¶

func Must4[T1 any, T2 any, T3 any, T4 any](v1 T1, v2 T2, v3 T3, v4 T4, err error) (T1, T2, T3, T4)

Same as `Must` but supporting 4 return values.
