func ElvisF ¶ added in v0.0.2024072421
func ElvisF[T comparable]( t func() T, f func() T, ) (ret T)
ElvisF returns the result of the first function if it is not empty, otherwise the result of the second function.
func ErrorAs ¶ added in v0.0.2024080520
ErrorAs returns the error as the type T if possible, otherwise returns nil.
func Expect ¶ added in v0.0.2024073012
Expect expects the error to be nil or one of the errors passed as arguments.

func Ternary ¶
Ternary returns the first value if cond is true, otherwise the second value. // Ternary conditional operator - Wikipedia https://en.wikipedia.org/wiki/Ternary_conditional_operator
func TernaryF ¶
TernaryF returns the result of the first function if cond is true, otherwise the result of the second function.
func TernaryF2 ¶ added in v0.0.2024072004
