composeErrors

fun ~~composeErrors~~(first: Throwable, res: Result<Any?>): Throwable

Deprecated

Niche use-case, prefer using higher level operators or addSuppressed from Kotlin Std

Replace with

res.fold({ first }, { e -> first.apply { addSuppressed(e) } })

fun ~~composeErrors~~(first: Throwable, vararg rest: Throwable): Throwable

fun ~~composeErrors~~(first: Throwable, rest: List<Throwable>): Throwable

Deprecated

Niche use-case, prefer using higher level operators or addSuppressed from Kotlin Std

Replace with

first.apply { rest.forEach(::addSuppressed) }

Composes multiple errors together, meant for those cases in which error suppression, due to a second error being triggered, is not acceptable.

On top of the JVM this function uses Throwable#addSuppressed, available since Java 7. On top of JavaScript the function would return a CompositeException.
