Methods

ToResultAsync<TValue>(Task<Maybe<TValue>>, Error)

Asynchronously converts a Maybe<T> to a Result<TValue>. If the Maybe has a value, returns success; otherwise, returns failure with the specified error.

public static Task<Result<TValue>> ToResultAsync<TValue>(this Task<Maybe<TValue>> maybeTask, Error error) where TValue : notnull

Parameters

maybeTask Task<Maybe<TValue>>

The task containing the Maybe instance to convert.

error Error

The error to return if the Maybe has no value.

Returns

Task<Result<TValue>>

A task containing a Result with the Maybe's value or the specified error.

Type Parameters

TValue

Type of the value contained in Maybe.

ToResultAsync<TValue>(Task<Maybe<TValue>>, Func<Error>)

Asynchronously converts a Maybe<T> to a Result<TValue> using a function to create the error. If the Maybe has a value, returns success; otherwise, returns failure with an error from the function.

public static Task<Result<TValue>> ToResultAsync<TValue>(this Task<Maybe<TValue>> maybeTask, Func<Error> ferror) where TValue : notnull

Parameters

maybeTask Task<Maybe<TValue>>

The task containing the Maybe instance to convert.

ferror Func<Error>

A function that produces the error if the Maybe has no value.

Returns

Task<Result<TValue>>

A task containing a Result with the Maybe's value or an error from the function.

Type Parameters

TValue

Type of the value contained in Maybe.

ToResultAsync<TValue>(ValueTask<Maybe<TValue>>, Error)

Asynchronously converts a Maybe<T> to a Result<TValue> using a ValueTask. If the Maybe has a value, returns success; otherwise, returns failure with the specified error.

public static ValueTask<Result<TValue>> ToResultAsync<TValue>(this ValueTask<Maybe<TValue>> maybeTask, Error error) where TValue : notnull

Parameters

maybeTask ValueTask<Maybe<TValue>>

The ValueTask containing the Maybe instance to convert.

error Error

The error to return if the Maybe has no value.

Returns

ValueTask<Result<TValue>>

A ValueTask containing a Result with the Maybe's value or the specified error.

Type Parameters

TValue

Type of the value contained in Maybe.

ToResultAsync<TValue>(ValueTask<Maybe<TValue>>, Func<Error>)

Asynchronously converts a Maybe<T> to a Result<TValue> using a ValueTask and a function to create the error. If the Maybe has a value, returns success; otherwise, returns failure with an error from the function.

public static ValueTask<Result<TValue>> ToResultAsync<TValue>(this ValueTask<Maybe<TValue>> maybeTask, Func<Error> ferror) where TValue : notnull

Parameters

maybeTask ValueTask<Maybe<TValue>>

The ValueTask containing the Maybe instance to convert.

ferror Func<Error>

A function that produces the error if the Maybe has no value.

Returns

ValueTask<Result<TValue>>

A ValueTask containing a Result with the Maybe's value or an error from the function.

Type Parameters

TValue

Type of the value contained in Maybe.
