Assembly

Trellis.Core.dll

Remarks

BindZip differs from Bind in that it preserves the original value(s) and appends the new value.

var result = GetOrder(id)
    .BindZip(order => GetCustomer(order.CustomerId))
    .BindZip((order, customer) => GetInventory(order.ProductId))
    .BindZip((order, customer, inventory) => CalculateShipping(order, inventory));

Methods

BindZip<T1, T2>(Result<T1>, Func<T1, Result<T2>>)

Binds a function to the Result value and zips both values into a tuple on success. If the source or the function result is a failure, returns that failure.

public static Result<(T1, T2)> BindZip<T1, T2>(this Result<T1> result, Func<T1, Result<T2>> func)

Parameters

result Result<T1>

The result to bind and zip.

func Func<T1, Result<T2>>

The function to call if the result is successful.

Returns

Result<(T1, T2)>

A tuple result combining both values on success; otherwise the failure.

Type Parameters

T1

Type of the input result value.

T2

Type of the new result value.

BindZip<T1, T2, T3>(Result<(T1, T2)>, Func<T1, T2, Result<T3>>)

Binds a function that receives a 2-tuple's components and zips the result into a 3-tuple. If the source or the function result is a failure, returns that failure.

public static Result<(T1, T2, T3)> BindZip<T1, T2, T3>(this Result<(T1, T2)> result, Func<T1, T2, Result<T3>> func)

Parameters

result Result<(T1, T2)>
