[PATCH v2 3/3] rust: macros: simplify Result<()> in function returns

[Manas via B4 Relay]

From: Manas <manas18244@xxxxxxxxxxx>

Functions foo and bar in doctests return `Result<()>` type. This type
can be simply written as `Result` as default type parameters are unit
`()` and `Error` types. This also keeps the usage of `Result`
consistent.
