Remarks

Bind is the core operation in Railway Oriented Programming. It allows you to chain together operations that can fail, automatically short-circuiting on the first failure. If the input Result is a success, the bind function is called with the value. If the input Result is a failure, the bind function is skipped and the failure is propagated.

Methods

Bind<TValue, TResult>(Result<TValue>, Func<TValue, Result<TResult>>)

Binds the result to a function that returns a new result. If the starting result is a success, the function is called with the value. If the starting result is a failure, the function is skipped and the failure is returned.

public static Result<TResult> Bind<TValue, TResult>(this Result<TValue> result, Func<TValue, Result<TResult>> func)

Parameters

result Result<TValue>

The result to bind.

func Func<TValue, Result<TResult>>

The function to call if the result is successful.

Returns

Result<TResult>

A new result from the function if success; otherwise the original failure.

Type Parameters

TValue

Type of the input result value.

TResult

Type of the output result value.
