compose

Overview ¶

Package compose contains the implementation of the compose plugin, which generates the deriveCompose function.

The deriveCompose function composes multiple functions that return an error into one function.

deriveCompose(func() (A, error), func(A) (B, error)) func() (B, error)
deriveCompose(func(A) (B, error), func(B) (C, error)) func(A) (C, error)
deriveCompose(func(A...) (B..., error), func(B...) (C..., error)) func(A...) (C..., error)
deriveCompose(func(A...) (B..., error), ..., func(C...) (D..., error)) func(A...) (D..., error)
