Struct Result<T, TError> | .NEXT

Represents a result of operation which can be actual result or error code.

public readonly struct Result<T, TError> : IResultMonad<T, TError, Result<T, TError>>, IResultMonad<T, TError>, IOptionMonad<T, Result<T, TError>>, IOptionMonad<T>, ISupplier<object?>, IFunctional<Func<object?>> where TError : struct, Enum

The type of the result.

The type of the error code. Default value must represent the successful result.

Initializes a new successful result.

The result value.

Initializes a new unsuccessful result.

public Result(TError error)

The error code.

Gets the error code.

public TError Error { get; }

Indicates that the result is successful.

public bool IsSuccessful { get; }

true if this result is successful; false if this result represents exception.

Extracts the actual result.

Returns the value if present; otherwise return default value.

public T? ValueOrDefault { get; }

The value, if present, otherwise default.

Gets a reference to the underlying value.

[JsonIgnore]
public ref readonly T ValueRef { get; }

The reference to the result.

Gets boxed representation of the result.

public Result<object?, TError> Box()

The boxed representation of the result.

If the successful result is present, apply the provided mapping function hiding any exception caused by the converter.

[CLSCompliant(false)]
public Result<TResult, TError> Convert<TResult>(delegate*<T, TResult> converter)

A mapping function to be applied to the value, if present.

The conversion result.

The type of the mapping function result.

If the successful result is present, apply the provided mapping function hiding any exception caused by the converter.

public Result<TResult, TError> Convert<TResult>(Converter<T, TResult> converter)

A mapping function to be applied to the value, if present.

The conversion result.

The type of the mapping function result.

Returns the value if present; otherwise return default value.

public T? Or(T? defaultValue)

The value to be returned if this result is unsuccessful.

The value, if present, otherwise defaultValue.

Returns the value if present; otherwise invoke delegate.

[CLSCompliant(false)]
public T OrInvoke(delegate*<TError, T> defaultFunc)

A delegate to be invoked if value is not present.

The value, if present, otherwise returned from delegate.

Returns the value if present; otherwise invoke delegate.

[CLSCompliant(false)]
public T OrInvoke(delegate*<TError, T> defaultFunc)

A delegate to be invoked if value is not present.

The value, if present, otherwise returned from delegate.

Returns the value if present; otherwise invoke delegate.

public T OrInvoke(Func<T> defaultFunc)

A delegate to be invoked if value is not present.

The value, if present, otherwise returned from delegate.

Returns the value if present; otherwise invoke delegate.

public T OrInvoke(Func<TError, T> defaultFunc)

A delegate to be invoked if value is not present.

The value, if present, otherwise returned from delegate.

Gets underlying value or throws an exception.

[CLSCompliant(false)]
public T OrThrow(delegate*<TError, Exception> exceptionFactory)

The exception factory that accepts the error code.

The underlying value.

The result is unsuccessful.

Gets underlying value or throws an exception.

public T OrThrow(Func<TError, Exception> exceptionFactory)

The exception factory that accepts the error code.

The underlying value.

The result is unsuccessful.

Converts this result into Result<T>.

public Result<T> ToResult()

The converted result.

Returns textual representation of this object.

public override string? ToString()

The textual representation of this object.

Converts the result into Optional<T>.

public Optional<T> TryGet()

Option monad representing value in this monad.

Attempts to extract value from the container if it is present.

public bool TryGet(out T value)

Extracted value.

true if value is present; otherwise, false.

Indicates that both results are successful.

public static bool operator &(in Result<T, TError> left, in Result<T, TError> right)

The first result to check.

The second result to check.

true if both results are successful; otherwise, false.

Tries to return successful result.

public static Result<T, TError> operator |(in Result<T, TError> x, in Result<T, TError> y)

The first container.

The second container.

The first successful result.

Returns the value if present; otherwise return default value.

public static T? operator |(in Result<T, TError> result, T? defaultValue)

The result to check.

The value to be returned if this result is unsuccessful.

The value, if present, otherwise defaultValue.

Extracts actual result.

public static explicit operator T(in Result<T, TError> result)

The result object.

Checks whether the container has no value.

public static bool operator false(in Result<T, TError> result)

true if this container has no value; otherwise, false.

Converts the result into Optional<T>.

public static implicit operator Optional<T>(in Result<T, TError> result)

The result to be converted.

Option monad representing value in this monad.

Converts the result into Result<T>.

public static implicit operator Result<T>(in Result<T, TError> result)

The result to be converted.

The converted result.

Converts value into the result.

public static implicit operator Result<T, TError>(T result)

The result to be converted.

The result representing result value.

Checks whether the container has no value.

public static bool operator !(in Result<T, TError> result)

true if this container has no value; otherwise, false.

Checks whether the container has value.

public static bool operator true(in Result<T, TError> result)

true if this container has value; otherwise, false.
