Functions

Function	Description
`flatMap`	Chains a success through transform, which itself returns a Result.
`fold`	Applies onSuccess or onFailure depending on the result variant.
`getOrNull`	Returns the success value, or null if this is a Result.Failure.
`getOrThrow`	Returns the success value, or throws if this is a Result.Failure.
`map`	Transforms the success value using transform, leaving failures unchanged.
`mapError`	Transforms the error using transform, leaving successes unchanged.

inline fun <T, E, R> Result<T, E>.flatMap(transform: (T) -> Result<R, E>): Result<R, E>

Chains a success through transform, which itself returns a Result.

inline fun <T, E> Result<T, E>.fold(onSuccess: (T) -> Unit, onFailure: (E) -> Unit)

Applies onSuccess or onFailure depending on the result variant.

fun <T, E> Result<T, E>.getOrNull(): T?

Returns the success value, or null if this is a Result.Failure.

fun <T, E> Result<T, E>.getOrThrow(): T

Returns the success value, or throws if this is a Result.Failure.

inline fun <T, E, R> Result<T, E>.map(transform: (T) -> R): Result<R, E>

Transforms the success value using transform, leaving failures unchanged.

inline fun <T, E, F> Result<T, E>.mapError(transform: (E) -> F): Result<T, F>

Transforms the error using transform, leaving successes unchanged.
