Sebastian Dröge 107ae588f2 examples: Fix various clippy warnings 2019-10-04 11:01:55 +03:00
Sebastian Dröge 06cfcd57fc Move to_string() methods into the Display trait or rename to to_str(), move from_string() into the FromStr trait 
Fixes clippy warnings, prevents confusing errors and is more consistent.

The Display trait provides a to_string() method by itself and FromStr
provides from_str().

Sebastian Dröge 8618085d46 Port examples/tutorials to the explicit Option parameter changes 2019-04-15 19:19:19 +03:00
François Laignel 948fb2ae4b Replace XXXReturn with Result<XXXSuccess, XXXError> 
... in function signatures.

These breaking changes aim at improving usability by allowing users
to take advantage of Rust error management features sur as `ok_or`,
`map_err`, `expect` and the `?` operator. See the `examples` and
`tutorials` to get an idea of the impacts.
