Methods

TapOnFailure<TValue, TError>(Result<TValue, TError>, Action<TError>)

Executes a side effect on the error value and returns the original result unchanged. The action is not called if the result is a success.

public static Result<TValue, TError> TapOnFailure<TValue, TError>(this Result<TValue, TError> result, Action<TError> action) where TError : IError

Parameters

result Result<TValue, TError>

The result to tap into.

action Action<TError>

The side effect to run on failure.

Returns

Result<TValue, TError>

The original result, unchanged.

Type Parameters

TValue

The value type.

TError

The error type. Must implement IError.

Examples
